Answer: y = 42°
Step-by-step explanation: You can find the second angle in that triangle because it is next to another 90° angle. Then you add 90 and 48 and subtract that number from 180 and you get 42. Hope this helps!

Given f(x)=2x+1 and g(x)=7-x. Find g(f(x)).
Answer:
f(g(x)) = 2(7 - x) + 1
Step-by-step explanation:
f(x) = 2x + 1
g(x) = 7 - x
The question in the picture itself says to find f(g(x)) so i'll find that instead
f(g(x)) = 2(7 - x) + 1
f(g(x)) = 14 - 2x + 1
f(g(x)) = -2x + 15
Find the value of X.
Answer:
35
Step-by-step explanation:
x + 10 = 45
x = 35
Answer:
x=35
Step-by-step explanation:
Opposite sides are equal so angle MNL is equal to JNK.
THerefore, JNK is 45 degrees.
So, x+10=45. We can simplify this to x=35.
Hope that helps!

perimeter = 300m
Step-by-step explanation:
area=l×w
area=l×50
area=50l
5000=50l
l=100
perimeter =2(l+w)
perimeter=2(100+50)

Answer:
Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. ... A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.

What is the solution for the system of equations? Use the substitution method to solve. 2x+y=20−5y=−6x+12 Enter your answer by filling in the boxes. ( , )
Answer:
(7, 6 )
Step-by-step explanation:
2x + y = 20 ( subtract 2x from both sides )
y = 20 - 2x → (1)
- 5y = - 6x + 12 → (2)
Substitute y = 20 - 2x into (2)
- 5(20 - 2x) = - 6x + 12 ← distribute parenthesis on left side
- 100 + 10x = - 6x + 12 ( add 6x to both sides )
- 100 + 16x = 12 ( add 100 to both sides )
16x = 112 ( divide both sides by 16 )
x = 7
Substitute x = 7 into (1)
y = 20 - 2(7) = 20 - 14 = 6
solution is (7, 6 )
Answer: (7,6)
Step-by-step explanation:
can someone help me please, this is so stressful:/
Answer:
x=2
Step-by-step explanation:
To solve for x, you want to isolate it. To do this, move terms that are NOT x and use the opposite operation to get it to the other side.
10x - 3 = 17
(Add 3 to both sides)
10x = 20
Now isolate x (since 10x is really 10 * x, you divide)
10x=20
x=2
This is how you would solve to get the solution.

To make some additional money, Vanessa began to
walk her sister's dog in order to help the dog lose
weight. Each week, the dog lost 0.2 pounds of weight
from walking with Vanessa. If the dog's starting weight
was 40 pounds, find the number of weeks that it will
take for the dog to weigh 38 pounds.
write an equation and isolate the variable.
Answer:
10 weeks
Step-by-step explanation:
Initial weight: 40
1 week = 0.2 lbs lost
40 - 38 = 2 lbs lost (goal)
x = number of weeks
0.2*x = 2
0.2x = 2
x = 10
Can anyone help me with this please I really need help with this rq .
Answer:
Step-by-step explanation:
g(x) = ax - b
-76 = 27a - b
-79 = 28a - b Subtract
3 = -a Multiply both sides by -1
a = -3
g(x) = -3x - b
-85 = -3*30 - b
-85 = - 90 - b Add 90 to both sides
90-85 = - b Combine
5 = - b Multiply both sides by - 1
-5 = b
g(x) = -3x - b
g(x) = -3x - (-5)
g(x) = - 3x + 5

The organizers of a conference needs to prepare at least 200 notepads for the event
and have a budget of $160 for the notepads. A store sells notepads in packages of 24
and packages of 6.
24x + 6y > 200
This system of inequalities represent these constraints:
(16x + 5.40y = 160
The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160
Inequalities shows the non equal comparison of numbers or expressions.
Let x represent the number of packages of 24 notepads and y represent the number of packages of 6 notepads
Since the organizers need to do at least 200 notepads, hence:
24x + 6y > 200
Also, they have a budget of $160. Let us assume that each 24 package cost $16 and each 6 package cost $5.40, hence:
16x + 5.40y ≤ 160
The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160

Use the distributive property to write an expression equivalent to 8(35).
Drag and drop the appropriate number into each box.
Answer:
280
Step-by-step explanation:
8(35) can be re-written as 8(30 + 5). This, in turn, is 240 + 40, or 280. This approach makes use of the Distribution Property of Multiplication.
