can someone help me with my test i have too write out the whole entire process & simplify them -
1st -3(2x-5)
2nd - 5+3x-8y+2x+9y-12
Answer:
1st -6x + 15
2nd 5x + y - 17
Simplified = -x + y -2
Step-by-step explanation:
Just add like terms if that's what it's asking.
Parallel or perpendicular 3x+5y=10 and 5x-3y=-6
When = 3, what will the value for y be for the equation - 4x + 5y = 18?
If x equals 3 then y must equal 1.2
Answer: y=6
-4(3)+5y=18
-12+5y=18
add 12 to both sides
-12+5y+12=18+12
5y=18+12
5y=30
divide both sides by 5
5y÷5=30÷5
y=30÷5
y=6

Mario walked at a rate of 5/6 miles every 10 minutes what is his unit rate every mile per hour
Answer:
Mario's unit rate is 5/1
Step-by-step explanation:
We know that Mario walks 5/6 miles per 10 minutes.
We need to find out how many miles Mario walks in 60 minutes (1 hour).
10 * 6 = 60. Which means that we must multiply 5/6 by 6.
[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]
30/6 = 5
Mario walks 5 miles per hour.
To put this in to a unit rate we must put this is a fraction:
[tex]\frac{Miles}{Hour}[/tex]
Substitute:
5/1
Answer:
Mario's unit rate is given by 900 miles/hour
Step-by-step explanation:
We have been given that Mario walked at a rate of 2/3 miles every 10 minutes
We have the relation between speed, time and distance, which is given by
speed = distance/Time
we have,
distance = 2/3 miles
Time = 10 minutes
On substituting these values in above formula, we got
speed 2/3 /10
speed 2/10.3
We have to find the unit rate in mile per hour, so we need to multiply it by 60
Thus, unit rate is given by
1/15 X 60
= 4 miles/hour

1.Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many miles does the first cyclist bike in 45 minutes?
Answer:
9 miles
Step-by-step explanation:
If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.
30+15=45
6+3=9
The first cyclist bikes 9 miles in 45 minutes.
Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:
60 = 12 45 = X 45 x 12/60 = X 540/60 = X 9 = X
Therefore, the first cyclist bikes 9 miles in 45 minutes.

This table represents the number of ounces, u, a kitten grows after w, weeks. When graphed, all of the points in the table lie on the same line. What is the slope and y-intercept of the line? slope=−23, y-intercept=−0.2 slope=32, y-intercept = 3 slope=23, y-intercept=−0.2 slope=−32, y-intercept = 3
Using the slope and intercept formula, the slope and y - intercept values of the graphed data are 3/2 and 3 respectively
Given the data :
Weeks, w ___ Weight in ounces, u
0 __________ 3
3 _________ 7.5
6 __________12
9 _________16.5
The y - intercept :
This is the value of y when the value of x = 0From the table given, the initial weight of the kitten (weight at week 0) = 3 ounces
Hence, the intercept is 3 ounces.
2.)
The slope :
Slope = Rise / RunRise = y2 - y1 = (16.5 - 3) = 13.5
Run = x2 - x1 = 9 - 0 = 9
Slope = 13.5 / 9 = 1.5
Therefore, the slope is 1.5

It takes Austin 8 hours longer than Elliott to construct a wooden chair in shop class. When the classmates work together, they can complete one chair in 3 hours. This situation can be represented by this expression, where t is the amount of time, in hours, it takes Elliott to complete a chair on his own.
The equivalent expression obtained using the least common multiple concept is [tex] \frac{6t + 24}{t^{2} +8}[/tex]
To solve, we need to obtain the L. C. M of the denominator values :
The L. C. M of t and t + 8 = [tex] t^{2} + 8t[/tex]
Hence,
[tex]\frac{3}{t} + \frac{3}{t+8} = \frac{6t + 24}{t^{2} +8}[/tex]

Answer:
PQ=30
Step-by-step explanation:
Knowing that the segment has 3 parts that are 3:1:1 and sum up to 50, you could find how much 1 would equal by finding the total in relation to the ratio (doing 3+1+1) which gets you 5 parts. Then you can divide the total (50) by 5 to figure out how much one part would equal (10). Now, since you know that 1 part is equal to 10 and that PQ is 3 parts, you can find that PQ is equal to 3x10, or 30.

Jaxon was asked 40 questions on a test he answered 80% incorrectly how many did he get correct
Answer:
8 correct.
Step-by-step explanation:
80 / 100 = x / 40 (Since he got 80% INCORRECT you will subtract the value of x from 40)
100x = 80 x 40
x = 3200 / 100
x = 32
40 - 32 = 8
