Step-by-step explanation:
Givens
4 scones
1 loaf of bread
Total cost = 3.30
Equation
Let the loaf of bread = b
Let the scones = s
Cost = b + 4s
Solution
Substitute the givens into the equation
b + 4s = Cost
90 + 4s = 3.30 Subtract 90 from both sides
90-90 + 4s = 3.30-90 Combine
4s = 2.40 Divide by 4
4s/4 = 2.40/4
s = 0.6 of a pound

Step-by-step explanation:
A ratio is a relation between two numbers.
*A ratio determines how many times 20 contains/values 8.
<u>A ratio representing the width to the length is: </u>
8:20.
8 represents the width, 20 represents the length.
To simplify a ratio, you must divide each side by the same number.
<u>S</u><u>i</u><u>mplified </u><u>ratios</u><u> </u><u>are</u><u>:</u>
4:10 (Divide by 2)
2:5 (Divide by 4)
1:2.5 (Divide by 8)
The ratio is detailing that the length is 2.5 times larger than the width.
<u>Your answers are;</u>
8:20
4:10
2:5
1:2.5
Answer:
x=4.75
Step-by-step explanation:
16(4x-3)=8(2x+4)
16*4x-3=8*2x+4
-2x -2x
16*2x-3=8*4
multiply 8*4=32
16*4x-3=32
-16 -16
4x-3=16
+3 +3
4x=19
divide 4 by both sides
x=4.75
Answer: Writing an equation in function form. You want to remove the x term from the side y is on and move it to the other side of the equal sign. To do this either add or subtract the x term from both sides. Next divide by the coefficient of the y term. Now your equation is in function form.
