An angle measures 40° less than the measure of its supplementary angle. What is the measure of each angle? please hlpppppp

nordsb [41]

Answer:

Step-by-step explanation:

Two supplementary angles add up to 180°

Suppose x + y = 180 and y = x - 40

first we substitute y by x - 40 in the equation x + y = 180 ,we get:

x + (x - 40) = 180

then

2x - 40 = 180

then

2x = 180 + 40

= 220

then

x = 220/2

= 110

therefore

y = 110 - 40

= 70

Ellie's favorite recipe requires 3 eggs and makes 6 servings. Grace modifies the recipe by using 7 eggs and increasing all other

grandymaker [24]

The modified recipe will make 14 servings.

Step-by-step explanation:

Given,

Eggs used = 3

Servings made = 6

Ratio of eggs to servings = 3:6

Eggs used in modified recipes = 7

Let,

x be the number of servings = x

Ratio of eggs to servings = 7:x

Using proportion;

Eggs to servings :: Eggs to servings

3:6::7:x

Product of mean = Product of extreme

$6*7=3*x\\42=3x\\3x=42$

Dividing both sides by 3

$\frac{3x}{3}=\frac{42}{3}\\x=14$

The modified recipe will make 14 servings.
