Answer:

1 $\frac{3}{5}$ cups of strawberries

Step-by-step explanation:

To find how much you will need for 2 pies, multiply 4/5 by 2:

4/5(2)

= 8/5

Simplify this to a mixed number:

= 1 $\frac{3}{5}$

So, you will need 1 $\frac{3}{5}$ cups of strawberries to make 2 pies

Answer:

Step-by-step explanation:

Let the two numbers be 2x and 3x.

According to the question,

2x+3x=45

5x=45

x=45/5

x=9

so th required numbers are 18 and 27 as

2x=2*9=18

3x=3*9=27

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times

mafiozo [28]

Answer:

a = 30°

b = 70°

c = 80°

Step-by-step explanation:

Hi there !

a ; b ; c = angles

a + b + c = 180°

b + c = 5a

replace (b + c)

a + (b + c) = 180

a + 5a = 180

6a = 180

a = 30°

b + c = 180 - a

b + c = 150

c = b + 10

replace c

b + (b + 10) = 150

2b = 150 - 10

2b = 140

b = 70°

c = b + 10

c = 80°

Good luck !

PLEASE HELP!! MATH QUESTION!! 20 points!!

7, 11 are linear.
9 is a quadratic. y = 2x^2 - 3

Problem 11
First find the slope. Use the first two points to do that.
y2 = 8
y1 = 6
x2 = - 3
x1 = - 1

Sub and solve
y = (y2 - y1) / (x2 - x1)
y = (8 - 6) / (-3 - - 1)
y = 2/- 2
y = - 1

Step 2
Find the y intercept
So far we have
y = - x + b
x = 0
y = 5
5 = 0 *-1 + b
b = 5

Answer
y = -x + 5

Problem 9
is the quadratic.

y = a*x^2 + b
when x = 0
y = - 3
y = ax^2 - 3 Now use any other point to solve for a.

Use (2,5)
5 = a(2)^2 - 3 Add 3 to both sides.
5 + 3 = a*4
8 = 4a Divide by 4
8/4 = a
2 = a

check
Use (-1,1) to check
y = 2x^2 - 3
y = 2(-1)^2 - 3
y = 2*1 - 3
y = 2 - 3
y = - 1 Which is as it should be.

Problem 7
Is linear. Do the same way as 11.
The graph is included below.

See if you can get the equation line.

You should get
y = 2x - 4
