Answer:

x = 0.75

Step-by-step explanation:

(I'm probably wrong) if you ment 2x + 10x= 15 then 2 x ? = 1.5 so 1.5 ÷ 2 = 0.75 therefor 2 x 0.75 = 1.5 then 1.5 x 10 would equal 15. I do realise I'm probably wrong but that is my answer

8/t = 7/ 35

Dividing by 7

8/t = 7/ 35

8/ 7t = 1/ 35

Multiplying by t

8/7 = t/35

_____________

Options

1) 8/t = 35/ 7 (False, t/8 = 35/ 7 )

2) t/8 = 7/ 35 (False, t/8 = 35/ 7 )

3) 8/7 = t/ 35 (TRUE)

4) 7/8 = t/35 (False, 8/7 = t/ 35 )

75 + 50x = 25 + 70x<br><br> a, 5<br> b, 5/6<br> c, 2<br> d, 2.5
Stells [14]

Answer:

D

Step-by-step explanation:

Let's solve your equation step-by-step.

75+50x=25+70x

Step 1: Simplify both sides of the equation.

50x+75=70x+25

Step 2: Subtract 70x from both sides.

50x+75−70x=70x+25−70x

−20x+75=25

Step 3: Subtract 75 from both sides.

−20x+75−75=25−75

−20x=−50

Step 4: Divide both sides by -20.

−20x

−20

=

−50

−20

x=  5/2

For which value of x is line l parallel to line m?<br><br>A. 28<br>B. 62<br>C. 22<br>D. 68​
Rudiy27

For line l parallel to line m, the interior angles on the same side of the transversal should add upto 180° or in better words, they must be supplementary.

So, we can write that,

(2x + 6)° and 130° are supplementary.

⇛ 2x° + 6° + 130° = 180°

⇛ 2x° + 136° = 180°

⇛ 2x° = 44°

⇛ x° = 22°

The value of x for which line l is parallel to line m,

\large{ \boxed{ \bf{ \red{x = 22 \degree}}}}

And we are done !!
