What is the value of 10r - 5s +24 when r = 3 and s = 9?

Answer:

The scale factor is 0.5

Step-by-step explanation:

Figure A is 4 blocks wide and 4 blocks tall, Figure B is 2 blocks tall and 2 blocks wide, to get Figure B from Figure A you would need to scale it down by half (0.5)

=7x+5

Answer:

49/2, 17/20

Step-by-step explanation:

24.5=245/10=245÷5/10÷5=49/2

0.85=85/100=85÷5/100÷5=17/20

Answer:

Mixed numbers

a)  24  1/2  

b) 85/100 = 17/20

Step-by-step explanation:

a) as they asked mixed number we only have to create a fraction for the decimal 0.5 = 1/2 and rewrite 24 1/2 = 24.5

If the question asked for lowest terms 24/5 then 24.5% = 245/1000 = 49/200

b) rewrite 0.85 as a fraction in lowest terms

0.85 = 85% = 85/100 = 17/20

Answer:

PLZ MARK ME BRAINLIEST.  

Step-by-step explanation:

Number Of Students who go to School by Walk  = 27

Number Of Students who go to School by Bus  = 45

Ratio of Student who go to School by Walk :  Bus  = 27 : 45

=> Ratio of Student who go to School by Walk :  Bus  = 3 : 5

Hence Ratio of Student who walk to students who ride the Bus  is  3 : 5 is correct  -  True Statement

Number Of Students who go to School by Bike  = 21

Number Of Students who go to School by Walk  = 27

Ratio Bike : Walk = 21 : 27

=> Bike : Walk = 7 : 9

Hence for Every 7 Students who Bike there are 9 students who walk

=> For Every 7 Students who Bike there are 8 students who walk is not Correct

-> [tex](34-25)/40[/tex]

-> [tex]9/40[/tex]

Answer:

1/42

Step-by-step explanation:

4/7 - 23/42 = 24/42 - 23/42 = 1/42

Answer:

Step-by-step explanation:

[tex]\bigg(3^6\bigg)^{\frac{1}{2}}[/tex]

use

[tex](a^n)^m=a^{n\cdot m}[/tex]

[tex]\bigg(3^6\bigg)^{\frac{1}{2}}=3^{6\cdot\frac{1}{2}[/tex]

simplify

[tex]6\!\!\!\!\diagup^3\cdot\dfrac{1}{2\!\!\!\!\diagup_1}=3\cdot\dfrac{1}{1}=3\cdot1=3[/tex]

other

[tex]6\cdot\dfrac{1}{2}=\dfrac{6\cdot1}{2}=\dfrac{6}{2}=3[/tex]

therefore

Answer:

a/4x-3

Step-by-step explanation:

4 'x' box means: 4x, 3 '-' box means: -3

Answer:

a) 4x-3

I hope this helps have a great day

======================================================

Explanation:

Double everything in the second equation to go from x-y = 3 to 2x-2y = 6.

So we have this equivalent system of equations

[tex]\begin{cases}4x+2y = 6\\2x-2y=6\end{cases}[/tex]

We can then add straight down. The x terms add to 6x. The y terms go away because they add to 0. The stuff on the right hand sides add to 12.

After those three sets of addition operations, we have the new equation 6x = 12 which solves to x = 2 after dividing both sides by 6.

Now use x = 2 with any of the equations mentioned that have x,y involved so we can solve for y.

4x+2y = 6

4(2)+2y = 6

8+2y = 6

2y = 6-8

2y = -2

y = -2/2

y = -1

or we could say

x-y = 3

2-y = 3

-y = 3-2

-y = 1

y = -1

Either way, we get the same y value.

Since x = 2 and y = -1 pair up together, we get the ordered pair solution (x,y) = (2, -1). Therefore, the answer is choice D.

If you were to graph the two equations, as shown below, the two lines intersect at (2,-1). This point is on both lines at the same time. This is visual confirmation that the point is a solution to both equations. Though you should still algebraically check each original equation.

Answer:

y-3=5/4(x-10)

Step-by-step explanation:

The equation for point-slope form is y-y1=m(x-x1), where m is the slope and the coordinate is (x1,y1). Plug in the given values and presto!

Answer:

Step-by-step explanation:

With respect to angle Ф in the right triangle shown:

the opposite side is the leg LP, and

the adjacent side is the leg LM, and

the hypotenuse is MP.

The "perpendicular" is the leg LP, in which case the "base" is LM.  Notice that these two legs are perpendicular to one another.

Answer: W(t) = 4t + 2

Step-by-step explanation:

y = ax + b

Because you have already typed two pages, the y-intercept(b) will be 2

The slope(a) is the number of pages typed per hour, which is 4.

So if you put it together:

W(t) = 4t + 2

Answer:

measure a = 56

Step-by-step explanation:

Remember all angles on triangles equal up to 180, and it look that measure c is the same as measure b.

62+62=124

180-124=56

Therefore measure a is equal to 56, but I may be wrong, no one is perfect, but I hope this helps!

Answer: 2 over 7

Step-by-step explanation:

2/(2+5) = 2/7

Answer:

Part A

x is 46°

Part B

Alternate angles are angles that are in relatively opposite locations relative to a transversal

Step-by-step explanation:

Part A

∠DRP  = 110° (Given)

∠QPA = 64° (Given)

∠QPR =

Given that AB is parallel to CD, we have;

∠DRP is congruent to ∠APR (Alternate angles to a transversal RP of parallel lines AB and CD)

Therefore, ∠APR = 115°

∠APR = ∠QPA + ∠QPR (Angle addition postulate)

∴ 115° = 64° +  ∠QPR

∠QPR = 110° - 64° = 46°

x = 46°

Part B.

Given that AB is parallel to CD, the lines common (that intersects) both lines are the transversal lines

The angles formed between the parallel lines and the transversal lines have special relationships based on their position with respect to each other

In the question, the angle 110° given between CD and the transversal RP, is found to at an alternate position to the angle ∠APR between the same transversal RP and AB and given that alternate angles are always equal, angle ∠APR is therefore also equal to 110°.

Answer:

Question 2: The first function represents the amount of money she'll have from her 450 under her bed.

s(x) = 450

The second function represents the amount of money she'll earn from babysitting per hour (x):

a(x) = 6(x - 2)

To figure the combined amount, we can add the two functions:

f(x) = s(x) + a(x)

f(x) = 450 + 6(x - 2)

From there, she can simplify the function by distributing, then combining the like terms to simplify:

f(x) = 450 + 6x - 12

f(x) = 438 + 6x

Answer:

f(x) = 438 + 6x

Question 4: His functions are;

h(x)=$350

s(x)=(1.04)^x-1

To find total amount of money in Tommy's account using the functions above, we substitute the first equation x=$350 in the second function.

Answer:

dimensions: 4x5x3

volume: 60 cube inches

Step-by-step explanation:

assuming each cube is a one inch cube:

the dimensions of the prism are length 5 -inches, width 4 -inches and height 3 -inches. So, 4x5x3

the volume of a prism is the length x width x height, so the volume is 4x5x3 = 60 inches cubed.

Answer:

length = 5 inches

width  = 4 inches

height = 3 inches

So dimensions are 5 x 4 x 3 inches

Volume = l · w · h

V = 5 · 4 · 3 = 60 square inches.

Answer:

C: 3.5+1.5x=12.5

Step-by-step explanation:

i think this is correct because in the question they use the word Gain which means you would add. But also this answer is correct because the kitten had gain 1.5 pounds PER WEEK which make 1.5x

so your answer is 3.5+1.5x=12.5

Hope this helps have a good day

and if correct pls mark me brainliest

thank you bye

Answer:

3.5 +1.5x = 12.5 (third option top- down)

Step-by-step explanation:

given : weighted 3.5 lbs. then gained 1.5 lbs. per week ended up 12.5 lbs.

translate:             3.5                   +      1.5         *        x         =           12.5
