Answer:

i dont know how your teacher teaches it but in the first question take away the y after the 25. number 2 the start equation would be 55=2x+25 then you would subtract 25 from each side to get 30=2x, the divide by to to get x=15 or she made 15 calls. number 3 is correct.

11Alexandr11 [23.1K]

Answer: 28

Step-by-step explanation:

Let the number of balloons that she had last party be represented by x.

Since Mrs.Hines has 40 ballons for a party which was 12 more balloons than she had for her last party. The number of ballons had last party will be formed into an equation as:

x + 12 = 40

Collect like terms

x = 40 - 12

x = 28

She had 28 balloons last year

Michael is planting a garden in the shape of a right triangle. He wants 4 tickseed plants for each square meter of area. How man

Paladinen [302]

Answer:

336 plants

Step-by-step explanation:

To find the number of tickseed plants that Michael needs to plant in his garden, we have to find the area of the garden first.

We notice that the garden has the shape of a right triangle: so, we have to find the area of the right triangle.

The area of a triangle is given by the formula

$A=\frac{1}{2}bh$

where

A is the area

b is the length of the base

h is the height of the triangle

From the figure, we see that:

b = 7 m is the length of the base

h = 24 m is the height of the triangle

Therefore, applying the formula, we find the area of the garden:

$A=\frac{1}{2}7\cdot 24 =84 m^2$

We also know that Michael wants to plant 4 tickseed plants for each square meter of area; therefore, the total number of plants that Michael will plant is 4 times the area of the garden, so:

$N=4A=4\cdot 84=336$
