Answers

Answer 1

Answer:

100 red bricks

Step-by-step explanation:

Let's say red bricks is equal to 5x

Gray bricks is equal to 2x

We have an equation

2x + 5x = 140

= 7x = 140

Divide through by 7 to get the value of x

X = 140/7

X = 20

Red bricks = 5(x)

= 5(20)

= 100

Gray bricks = 2(x)

= 2(20)

= 40

Therefore in conclusion the number of red bricks is 100.

Using the Parallelogram Side Theorem Parallelogram A B C D is shown. Sides A B and D C are parallel. The length of A B is 4 q minus 8 and the length of D C is q + 4. What is the length of side AB of parallelogram ABCD? units

Answers

Answer: The length of AB = 8 units

Step-by-step explanation:

Given: In parallelogram ABCD, Sides A B and D C are parallel.

The length of AB is 4q minus 8 and the length of DC is q + 4.

Since opposite sides of parallelogram is parallel and equal.

So [tex]4q-8=q+4[/tex]

[tex]\Rightarrow\ 4q-q=4+8\\\\\Rightarrow\ 3q=12\\\\\Rightarrow\ q=4[/tex]

Length of AB = 4q-8=4(4)-8=16-8=8 units

Hnece, the length of AB = 8 units

The measure of an exterior angle of a triangle is x. The measure of the adjacent interior angle is at least twice x. List three possible solutions for x.​

Answers

Answer:

x=60°

x=48°

x=21°

Step-by-step explanation:

Inequalities

The sum of the exterior and the interior angle of a triangle is 180°.

The measure of an exterior angle of a triangle is called x, thus the interior angle is 180-x.

This angle is said to be at least twice x, thus:

180 - x ≥ 2x

Adding x:

180 ≥ 3x

Dividing by 3:

60 ≥ x

Swapping the inequality:

x ≤ 60°

The measure of x must be less or equal to 60°.

Three possible solutions are:

x=60°

x=48°

x=21°

Brent paid for six avocados with a $20 bill he received $10.40 in change construct and solve the equation can be used to find the price of each avocado

Answers

Step 1:
Work out how much is was for 6 avocados
20 - 10.40 = 9.6

Step 2:
Find out how much it is for 1 avocado
9.6 / 6 = $1.6

Step 3:
Construct an equation, where y is how many avocados
1.6y = total price

Answer is : D


Let's start with finding out how much he had to pay. 20-10.40 will give us that answer. That will equal the cost of 6 avocados, giving us an equation of
20 - 10.40 = 6p
Now we'll see which equations match this. Bingo! Answer number D is the same equation with 10.40 added on both sides.

Sign out Fred's bedroom has an area of 54 square feet. The bedroom is 6 times as many square feet as Fred's closet. If the closet is 3 feet wide, what is the length of the closet?

Answers

Answer:

3 feet

Step-by-step explanation:

Area of bedroom = 54 square feet.

Area of closet = Area of bedroom / 6= 54/6= 9 square feet.

Area = length * breadth

9 =  length *3

length = Area/ width

length = 9/3= 3 feet.

As the bedroom is having 6 times the area of the closet we will divide the area of the bedroom by 6 to get the area of the closet ( 54/6= 9) . Area is obtained by multiplying the length and the breadth so we have the width which 3 feet , we divide the area with the width ( 9/3= 3) to get the length = 3 feet.
