Answer:

Step-by-step explanation:

1.2/3 =0.4

4/5 can be written as 0.8

So, 1.8/0.8 = 2.25.

However, 1.8/4/5 is the same as:

1.8/1 ÷ 4/5

Keep Change Flip

1.8/1 x 5/4 = 9/4

(1.8 x 5=9 & 1 x4 =4)

9/4 =2.25

Answer question 4 please?

Grace [21]

Answer:

Step-by-step explanation:

Sides AB and AC are equal

So,

3x - 5 = 7

+ 5 on both sides

3x = 12

divide both sides by 3

x = 4

Now take the 2x and plug in x for 4.

2(4) = 8

Final answer is 8.

-1/3x+1=-7 negative one third x plus one equals negative seven

liraira [26]

Multiply both sides by -3 to get rid of the negative and the fraction.

X - 3 = 21

Move the constants over to isolate the variable

X = 24

What is the area of the figure below

jek_recluse [69]

Answer:

Option A

Step-by-step explanation:

Area of the composite figure = Area of ΔABH + Area of BCGH + Area of ΔDEF

Area of ΔABH = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(6)(8-5)$

= 9 in²

Area of the trapezoid = $\frac{1}{2}(CG+BH)(\text{Distance between these lines})$

= $\frac{1}{2}(6+4)(5)$

= 25 in²

Area of ΔDEF = $\frac{1}{2}(8)(6)$

= 24 in²

Therefore, area of the given figure = 9 + 25 + 24

= 58 in²

Option A will be the correct option.
