Answer:

Step-by-step explanation:

Geometry is not my best subject but here's what I did:

The sum of the angles in a triangle is 180 so if we add 4 and 8 we can get angle 6

--> 180 - (37+62)

--> 180 - 99

---> 81

The sum of the angles on a line intersected at a point = 180

180 - 81 = Angle 5

Angle 5 = 99

One number is 8 more than another number, and their sum is 16. What are the 2 numbers?

gayaneshka [121]

Answer:

x = 12

y = 4

Step-by-step explanation:

x + y = 16

x - y = 8

y + 8 = x

Replace x with y + 8 in the new equation

8 + 2y = 16 ----> we can minus 8 on both sides

2y = 8 -----> divide both sides by 2

y = 4

Now for the x value

x + 4 = 16 ----> minus 4 on both sides

x = 12

How many solutions does the following equation have?

RoseWind [281]

Answer:

There will be No solution for the equation $9x - 4 = - 3x + 5 + 12x$ . Option B is correct.

Step-by-step explanation:

We need to determine how many solutions the equation $9x - 4 = - 3x + 5 + 12x$ have.

Solving the equation and finding the solutions

$9x - 4 = - 3x + 5 + 12x$

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

$9x +3x-12x = 5 + 4$

Simplifying

$12x-12x = 9\\0=9$

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation $9x - 4 = - 3x + 5 + 12x$ . Option B is correct.

Divide 28 cans of soda into two groups so the ratio is 3 to 4

Natali5045456 [20]

Total units would be: 3+4 = 7

value of 1 unit = 28/7 = 4

ratio would be 3(4) & 4(4) = 12 & 16
