A=−23

Check your work

A+15=−8

1) Let A=−23

−23+15=−8

2) Simplify −23+15 to −8

−8=−8

The answer is correct

Answer:

AB = 17.3 cm

Step-by-step explanation:

We require to find the measure of ∠A then use the cosine ratio to calculate AB

sum the parts of the ratio 3 + 2 = 5 parts, then

90° ÷ 5 = 18° ← value of 1 part of ratio

∠A = 2 × 18° = 36°, thus

cos36° = $(adjacent)/(hypotenuse)$ = $(14)/(AB)$

Multiply both sides by AB

AB × cos36° = 14 ( divide both sides by cos36° )

AB = $(14)/(cos36)$ ≈ 17.3 cm

Rocky family recipe for macaroni and cheese makes 4 servings of 310 calories each. Rocky decided to make 1.5time the recipe. How many calories,are in rocky batch of Mac and cheese

Answers

There are 4 servings with 310 calories in each serving
310×4=1,240 calories altogether
Since any number times 1 is the number, you just focus on the .5
.5 is also $(1)/(2)$ which is half of a number
1,240×.5=620
1,240+620=1,860
There are 1,860 calories in the batch

This is the more deconstructed, longer way in doing it
So an easier way is simply multiply 1,240×1.5=1,860
