The sum of two numbers is 35. Three times the larger number is the same as 4 times the smaller number. Find the smaller number

1 answer:

3 0

If 35-x is the smaller number and x is the larger number, we can take that 3*x=4*(35-x)=140-4x. Subtracting 3x from both sides, we get 140-7x=0. Adding 7x to both sides, we get 140=7x. Lastly, we can divide both sides by 7 to get x=20

9x–42=5 is x = 11.

<u>Step-by-step explanation:</u>

9x- 42 = 5...

When we put x = 9

then we will get 81 - 42 =39

put x = 10 then

9(10) - 42 = 90 - 42 - 48

put x = 11

then 9(11) - 42 = 99-42 = 57

So x = 11 is the answer.

in ABC the measure of angle A is 2x+3 the measure of angle B is 4x+2 the measure of angle C is 2x-1 what are the measures of the

Virty [35]

IN A triangle, sum of all angles = 180 degrees

2x + 3 + 4x+2 + 2x -1 = 180

8x +4 = 180

8x = 176

x = 176 /8 = 22 degrees

the angles are A = 2(22)+3 = 44+3 = 47 DEGREES

B = 4(22)+2 = 88 + 2 = 90 DEGREES

C = 2(22) -1 44-1 = 43 DEGREES
