You have to set it up clearly and cleanly and neatly.
a).
3 and 1/4 = 13/4 = 26/8
2 and 1/2 = 5/2 = 20/8
5/8 = 5/8
Add the eighths: (26 + 20 + 5)/8 = 51/8 = 6 and 3/8
b).
We want to know how many times 1/4 goes into the total amount.
51/8 = 25.5/4
That's 25 full servings, with 1/2 serving left over.
==============================================
For me, this whole thing is much easier if you work it in decimals.
a).
3 and 1/4 = 3.25
2 and 1/2 = 2.50
5/8 = . . . . . 0.625
Add um up: 6.375 quarts
b).
A serving is 0.25 quart.
Divide 6.375 by 0.25 = 25.5 . . . 25 full servings, with 1/2 left for the kitchen help.
Answer:
y = 26x
Step-by-step explanation:
A function rule is the relationship between the input and output values.
The input (x) is the number of potatoes and the output (y) is the amount of carbohydrates.
Each potato has 26 g of carbohydrates, so the function rule is
y = 26x
Answer:
a) 2
Step-by-step explanation:
9x - 7 = 6x - 4
3x = 3
x = 1
when x = 1
y = 9x - 7 = 9(1) - 7 = 2
or
y = 6x - 4 = 6(1) - 4 = 2
Answer
a) 2
Answer:8
Step-by-step explanation:
Answer:
Step-by-step explanation:
Left Frame
Consecutive angles (angles that are one after another) add up to 180 degrees. (The are supplementary).
9x + 6x = 180o Combine like terms
15x = 180o Divide by 15
15x/15 =180/15
x = 12
===============
You could do this the way it is done in the more formal proof.
9x + 6x + 9x + 6x = 360 Combine like terms: each quadrilateral = 180o
30x = 360 Perform Division Property of equality
x = 360/30 Do the division
x = 12
Right frame
The left side of line 3 is the substitution property.
<A = 9x
<B = 6x
<C = 9x
<D = 6x
The left side of line 4 is 30x. This comes from 9+6 + 9 + 6
The right side of line 5 is the division property of equality
