please help quickly.
Answer:
x = 2, y = 5
Step-by-step explanation:
Given the 2 equations
y = - 2x + 9 → (1)
y = 4x - 3 → (2)
Substitute y = 4x - 3 into (1)
4x - 3 = - 2x + 9 ( add 2x to both sides )
6x - 3 = 9 ( add 3 to both sides )
6x = 12 ( divide both sides by 6 )x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 4(2) - 3 = 8 - 3 = 5
Then x = 2, y = 5
Help pleaseee.The answer has to be 50,40, or 90
Answer:
40
Step-by-step explanation:
We know that angle FGE is equal to 50 and angle GEC is equal to 90 degrees because of the square. Therefore, we add them together. 50+90=140. We know that a triangle is equal to 180 degrees so we have to subtract 140 from 180. 180-140 is equal to 40. Therefore, angle FCE is equal to 40.
If this has helped you please mark as brainliest
Answer:
<FCE = 40
Step-by-step explanation:
The sum of angles in a triangle is (180) degrees. This holds true for the given triangle. Therefore, one can form an equation,
<FGE + <FCE + <GEC = 180
Substitute,
50 + <FCE + 90 = 180
(Note that a box around an angle indicates that the angle measure is (90) degrees)
Simplify,
140 + m<FCE = 180
Inverse operations,
140 + <FCE = 180
<FCE = 40

Answer:
I only know the answer to number 13, and it is 61°
Step-by-step explanation:
Since I go to RSM, I learned something called a remote interior angle theorem. Basically, the exterior angle is equal to the two angles that are on the far side of the triangle. So if you do 145-74, you get 61°.
Answer: 61°
please help quick!!!
Answer:
75
Step-by-step explanation:
Volume = 1/2*B*H
So 10 times 3 times 5 divided by 1/2. 10 times 3 is 30, multiplied by 5 is 150.
150 divided by 0.5 (1/2) is 75.
1) Explain how angles are measured.

One serving of kettle corn has 180 calories and a mass of 30 grams. How many calorie are in 5 grams of the kettle corn?
a. 6
b. 10
c. 30
d. 36
Answer:
30 calories.
Step-by-step explanation:
First we need to know how many is one gram so do 180/30 to get 6. Then, since we are looking for the amount in 5 grams, multiply 6 by 5 to get 30.
Therefore, there are 30 calories in 5 grams.

which model shows 9 (3+6) = (9 x 3) + (9 x 6)?
NO LINKS OR FILES THANK YOU!!
Answer:
Look at the image.
Step-by-step explanation:
The required model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B. Option B is correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is an array?The array is a collection of things and shapes in a specific pattern.
Here,
Given that, to determine the model that represents 9 (3+6) = (9 x 3) + (9 x 6)
So 9 (3+6) = (9 x 3) + (9 x 6) represents the arrangement of squares in array form,
If in a pattern there are 9 rows there must be 3 and 6 columns or vice versa.,
So from the above definition, a model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B.

For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?
Remember money is rounded to the nearest hundredth.
Answer:
2 dollars
Step-by-step explanation:
Answer:
$1.72
Step-by-step explanation:
First, subtract the cupcake from the total
44.03-2.75=41.28
Find out the total number of cookies
8+16=24
Then divide the total cookie price by the total number of cookies
41.28÷24=1.72
Each cookie costs $1.72

Step-by-step explanation:
A) The bus rental would be the total cost or "C". So 700=250+3m.
B) Solve with properties of equality:
700 - 250 = 250 + 3m - 250
450 = 3m
450/3 = 3m/3
150 = m
150 miles
C) Check your answer by plugging the answer into the original equation:
C = 250 + 3(150)
C = 250 + 450
C = 700
