Answer:
Step-by-step explanation:
First off, this wouldn't make sense for a girl to be older than her mother or her father.
Second, mother is x years old. The girl is 2x years old. The father is x+5 years old. Total sum = 100.
So, we need to solve for x first.
2x + x + x+5 = 100
4x + 5 = 100
4x = 95
4x ÷ 4 = 95 ÷ 4
x = 23.75
Mother is 23 and 3 quarters, turning 24.
Daughter is 23.75 × 2 = 47 1/2 years old.
And the Father is 28 and 3 quarters, turning 29.
Answer:
11 < -3t
Step-by-step explanation:
-3⅔ > t
Divide both sides by -3, then reverse the inequality symbol as a result of that.

Answer: y int: (0,9) x int: (3,0)
Step-by-step explanation:
In slope intercept form, the equation is y=-3x+9. In the formula y=mx+b, we know b is the y intercept, so our y int. is 9. To find our x intercept, we set y=0. So, 0=-3x+9=>3x=9=>x=3
Answer:
-18
Step-by-step explanation:
Let x be our number. First we have to write our equation.
The product of a number and -8 is represented as -8x (-8 multiplied by x). Remember that 'product' signifies multiplication.
The result is eight times the sum of x and 36. This is represented as 8(x + 36). We add x and 36 first because 8 has been multiplied by the sum of those two numbers.
So our equation is:
-8x = 8(x + 36)
We can now solve for x. First, expand the bracket.
-8x = 8x + 288
Next, subtract 8x from both sides. This will give us only one term containing x, which will make it easier to solve.
-8x - 8x = 8x + 288 - 8x
-16x = 288
Divide both sides by -16
x = -18
