8 - 1 = 7
7 - 9 = -2
7 divided by -2 is -3.5
The slope is -3.5 now we need to find the y intercept.
To find the y intercept do -3.5 times 7 and you get -24.5.
Next do 8- -24.5 and you get 32.5 which is the y intercept.
The equation would be y = -3.5x + 32.5
There are 16 red velvet cupcakes.
42 chocolate + 28 red velvet = 70 cupcakes
(42/ 70 *100%)+ (28 / 70 *100%) = (70/70 * 100%)
60 % chocolate + 40% red velvet = 100% cupcake
24 chocolate + X red velvet = Y cupcake
Y cupcake = 24 / 60% = 40 cupcakes
X red velvet = 40 cupcakes * 40% = 16 red velvet.
OR
(24 / 60%) * 40% = 16 red velvet cupcakes

7
Step-by-step explanation:
because the answer to the question is 7
Answer:
Baseballs is: $10
Bats is: $4
Step-by-step explanation:
Let x represent bats
and y represent baseballs
So we have :
(1) 4x + 7y = 68
(2) x + y = 14 => y = 14 - x
Use substitution.
Substitute equation (2) into equation (1)
4x + 7(14 - x) = 68
Solve for x
4x + 98 -7x = 68
-3x + 98 = 68
-3x = -30
x = 10
Solve for y, replace x = 2 into equation (2)
y = 14 - 10 = 4, so y = 4
Since x represents bats and y represents baseballs, it cost $10 for the bats and $4 for the baseballs.
