What is -3x+13=16 help me with each step.
hoa [83]

-3x+13=16

Move +13 to the other side. Sign changes from +13 to -13.

-3x+13-13=16-13

-3x=16-13

-3x=3

Divide by -3 for both sides.

-3/-3x=3/-3

Cross out -3 and -3, divide by -3, then becomes 1*1*x=x

x=-1

Answer: x=-1

Can someone help me with this please - can you also give a step by step not just an answer
n200080 [17]

Answer:

The way I was taught to do it is to change value into a total fraction, then multiple the numerators together, multiply the denominators together, and finally reduce as far as possible.

7/9 x 5 2/5 = 7/9 x 27/5 = 189/45 = 4 9/45 = 4 1/5

1 3/4 x 4 1/6 = 7/4 x 25/6 = 175/24 = 7 7/24

Solve for the variable shown. Round answers to the nearest hundredth if needed.
Olenka [21]

Answer and Step-by-step explanation:

Question 4:

We need to solve for y, so we need to use the cosine trig function, which is adjacent divided by hypotenuse.

cos(21) = \frac{y}{18}\\\\18(cos(21)) = y = 16.8\\\\\\

Question 5:

We need to use the sine trig function, which is opposite divided by hypotenuse.

sin(43) = \frac{31}{x} \\\\x = \frac{31}{sin(43)} = 45.45
