4y+25=3y+20
4y+5=3y
***y=5***
so you plug y into both
4(5)+25 and 3(5)+20
45, 100, and 35 are the measurements of the angles.

White shapes and black shapes are used in a game some of the shapes are circles all other shapes are sqaures The ratio of the nu
melisa1 [442]

Answer:

The fraction of all the shapes are circles is \frac{9}{32}

Step-by-step explanation:

There are two types of the shapes in a game.

Circle

Square

The ratio of number of white shapes to the number of black shapes is 5 : 11.

Consider there are 50 white shapes and 110 black shapes.

The ratio of the number of white circles to the number of white squares is      3 : 7.

Here 3/10 of the white shapes are circle and 7/10 are white squares.

The number of white circles can be obtained as follows,

White circles = 3/10 × 50

= 50

The number of white squares can be obtained as follows,

White squares = 7/10 × 50

= 35

The number of black circles to the number of black squares is 3/8.

The number of black circles can be obtained as follows,

Black circles = 3/11 × 110

= 30

The number of black squares can be obtained as follows,

Black squares = 8/11 × 110

= 80

The total number of circles is 30 + 15 = 45 and the total number of shapes is 50 + 110 = 160.

The fractions of all the shapes are circles are 45/160 which is simplified to 9/32

The fraction of all the shapes are circles is 9/32

Leon solved the equation 29=x−37. What could Leon have done to solve the equation in one step?
telo118 [61]

Answer:

X = 66

Step-by-step explanation:

In one step, Leon could collect like terms by moving -37 across the equal sign to meet 29, such that -37 becomes +37 (that is, 29 + 37 = x) then x = 66.

Describe how to factor quadratics.
Feliz [49]

Answer:

Step 1:

Write the equation in the correct form. To be in the correct form, you must remove all parentheses from each side of the equation by distributing, combine all like terms, and finally set the equation equal to zero with the terms written in descending order.

Step 2:

Use a factoring strategies to factor the problem.

Step 3:

Use the Zero Product Property and set each factor containing a variable equal to zero.

Step 4:

Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side
