Step-by-step explanation:

y= 3x + 5

2(3x + 5) = 4x + 24

6x + 10 = 4x + 24

2x = 14

x = 7

y= 3(7) +5

y = 26

Measure of missing angle

Answers

Answer:

44 degrees.

Step-by-step explanation:

Since angle A is 46 degrees, and angle C is 90 degrees (because of the right angle) you add 46 and 90 (you get 136) then subtract it from 180 (since every triangle equals 180 degrees) which gets you to 44 degrees.

Answer:

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Volume = Bh = 17.5×10 = 175 cm³

At science camp, the kitchen served half of their blueberries with breakfast. After dinner, they put the remaining 5,270g, end text of berries on top of their ice cream dessert.
How many kilograms of blueberries did the science camp start with?

_____ kilograms?

Answers

The science camp started with 10.54 kilograms of blueberries.

To find the number of kilograms of blueberries the science camp started with, first need to calculate the initial weight of the berries.

Given that the remaining weight of blueberries after dinner was 5,270g, and this represents half of the total blueberries served, we can determine the total weight before serving by doubling the remaining weight.

Double the remaining weight: 5,270g x 2 = 10,540g

Now, we need to convert the weight from grams to kilograms since we're looking for the weight in kilograms.

1,000 grams in a kilogram, so we can divide weight in grams by 1,000.

Weight in kilograms: 10,540g ÷ 1,000 = 10.54kg

Therefore, the science camp started with 10.54 kilograms of blueberries.

A farmer sells 6.8 kilograms of apples and pears at the farmer's market. 4 5 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?

Answers

Answer:

As a decimal your answer: is 5.4 rounded to the nearest tenth. As a mixed number fraction your answer is: 5 11/25. As a improper fraction your answer is: 136/25.

Step-by-step explanation:

Basically what I did was just divide 6.8 by 4/5. Or you could change 4/5 in a decimal and divide like that, OR change 6.8 into a fraction which is what if did- I’ll show you below. But, it’s better to have all solutions to the problem.

1) change 6.8 into fraction: 34/5

2) rewrite: 34/5 divide by 4/5

3) multiply: 136/25

4) alternative forms:

A. Mixed number- 5 11/25

B. Decimal: 5.44 or 5.4 rounded to nearest tenth.
