Answer:

x = 17.331....

Step-by-step explanation:

Basically use Tan on the calculator to find x. Look up "soh cah toa" if you still dont understand what I am doing.

Tan(37) = opposite / adjacent = x / 23

x = Tan(37) (23)                    multiply by 23 on both sides to get this

x = 0.753.... (23)                   now multiply the tan value on the calculator

x = 17.331....

Answer:

x = 21

Step-by-step explanation:

35 + ?? = 7(5 + 3)

1. Expand the brackets on the right:

35 + x = 35 + 21

2. Cancel out 35 from both sides

x = 21

Answer:

66m, 35in?, 12m, 2km, 26cm

Step-by-step explanation:

22/17 = 1.294x51 = 66m

7/3 = 2.333x15? = 35in not sure if the number on the pic is 15

18/12 = 1.5x8 = 12m

6/27 = .2222x9 = 2km

6.5/2.5 = 2.6x10 = 26cm

Answer:

A. CB

Step-by-step explanation:

3 x 2 (C is a 3 by 2) matrix can be multiplied to a 2 x 2 (B is a 2 by 2) matrix since C has 2 columns that are equal to the number of rows in the second matrix B.

A way of checking if two matrices can be multiplied is to first check the number of columns the first matrix contains and then check the number of rows that the second matrix contains.

If the number of columns in the first matrix equal the number of rows in the second matrix then that means it is possible to multiply these matrices.

Answer:

After 7 months, the girls will have the same amount in their accounts. They will have 175.

Step-by-step explanation:

Maria:

Starts with $105

Adds $10 each month

Jana Rae:

Starts with $0

Adds $25 each month

Set up an equation for both Maria and Jana.

m will represent the number of months.

Maria: 105 + 10m

Jana: 0 + 25m

You can do guess and check.

Let’s say m is equal to 6.

Subsitute m with 6 for both equations and check if they both end up having the same answer.

Maria: 105 + 10(6) = 165

Jana: 0 + 25(6) = 150

Is 165 and 150 equivalent? No

Let’s try m = 7 and do that same thing.

Maria: 105 + 10(7) = 175

Jana: 0 + 25(7) = 175

Now is the answer equal? Yes

So therefore, after 7 months, the girls will have the same amount in their accounts. They will have 175.

Answer:

[tex] \huge\: x =9 \sqrt{ \boxed{3}} [/tex]

Step-by-step explanation:

Given is a 30°-60°-90° triangle and x is the length of side opposite to 60° angle.

[tex] \therefore \: x = \frac{ \sqrt{3} }{2} \times 18 \\ \\ \therefore \: x = \sqrt{3} \times 9 \\ \\ \huge\therefore \: x =9 \sqrt{ \boxed{3}} [/tex]

Answer:

Step-by-step explanation:

Step 1 to find gcf of  16x^2 -16+3  is factor out  the equation = (4x)^2  -13   =  (4x+13)(4x-13) So we factor to show one - and one + and then step 2 we then divide 4/4  -13/4 and 4/4 13/4  and cancel out 4/4 and see what we are left with =  x>+ - 13/4  = 3  1/4    we can now find gcf by working out 16x^2 = 16(3 1/4)^2 = 16(10.5625) = 169  and  the gcf of 169 and +- 13  =  13

Step-by-step explanation:

x = frac{−1}{2}y + frac{45}{2}

Answer:

y- intercept = [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + [tex]\frac{4}{5}[/tex] ← is in slope- intercept form

with y- intercept c = [tex]\frac{4}{5}[/tex]

Answer:

x ≈ - 0.14

Step-by-step explanation:

6(4x + 5) = 3(x + 8) + 3 ← distribute parenthesis on both sides

24x + 30 = 3x + 24 + 3 , simplify

24x + 30 = 3x + 27 ( subtract 3x from both sides )

21x + 30 = 27 ( subtract 30 from both sides )

21x = - 3 ( divide both sides by 21 )

x = [tex]\frac{-3}{21}[/tex] = - [tex]\frac{1}{7}[/tex] ≈ - 0.14 ( to the nearest hundredth )
