11 less than 7 times a number is 5 more than 6 times the number. find the number.
kolezko [41]

Let's translate the words into expressions:

11 less than 7 times a number is 7x-11

5 more than 6 times the number is 6x+5

So we have the equation

7x-11 = 6x+5

Subtract 6x from both sides:

x - 11 = 5

Add 11 to both sides:

x=16

VARVARA [1.3K]

Answer:

C) 6

Step-by-step explanation:

Alternate interior angles are congruent meaning that they are equal to each other sp 18x+2=110 is simplified to 18x=108. Then divide by 18 to get x equal to 6. Hope this helped and post more :)

Find the value of x and find whether the angles or supplementary or complementary.
Alborosie

Answer:

1) x = 31

2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).

Step-by-step explanation:

1) Since both angles add up to be a supplementary,

→ equation 1 + equation 2 = 180

→ (3x + 25) + (2x) = 180

Solving by applying algebra will give the answer "x = 31".

Hope this helps!
