Answer: 1) 8x + 2 = 90 1a. 11 2. 13x-10= 133 2a. 11

Both solve for 11.

Step-by-step explanation: 1) they’re both the same measure so they equal each other

Subtract 2 from each side 8x = 88 and x is 11

13x - 10 = 133 they’re both the same measures so they equal each other.

Add 10 to both sides because it’s already negative and 13x = 143 and you get 11

Answer:

11 for both

Answers

Answer:

x is 103 cause it is opposite angles and y is 77 180-103 hope this helps you

Answer: x=103° y=77°

Step-by-step explanation:

Opposite angles are always the same so, as x is opposite to 103°, it would be 103° too.

To work out what y is you would have to do 180-103=77°. The reason why is because angles on a straight line always add up to 180° and you can see that 103° and y are on the same line.

Hope this helps :)

£250 in the ratio 3 : 5​

Answers

Answer:

Let 3x and 2x are divided into 250.

Step-by-step explanation:

3x + 2x = 250

⇒ 5x = 250

⇒ x =  = 50

∴ 3x = 3 × 50 = 150 and

2x = 2 × 50 = 100

Thus, the required numbers are 150 and 100.

Write an equation in slope intercept form for the line that passes through (-2,3) and is parallel to the graph of y=-3/4x+4

Answers

Answer:

When the equation parallel the graph then the measure of the equation is - 3/4

Then the equation is y=-3/4x+c

By using the point(-2,3)

[tex] y = \frac{ - 3}{4} x + c \\ 3 = \frac{ - 3}{4} \times - 2 + c \\ 12 = 6 + 4c \\ 4c = 6 \\ c = \frac{3}{2} [/tex]

Then the equation is
