Answer:
- Yolanda is 28
- Zachary is 21
Step-by-step explanation:
Let y represent Yolanda's age now, and let d represent their difference in ages. Then Zachary is now y-d years old.
When Yolanda was Zachary's age (now), Zachary was (y-d) -d. Yolanda is now twice that age:
y = 2(y -2d)
4d = y . . . . . . eliminate parentheses, add 4d-y
__
When Zachary is as old as Yolanda is now, Yolanda will be y+d and the sum of their ages will be 63:
y + (y+d) = 63
2y + d = 63
Using the expression for y from above, we get ...
2(4d) +d = 63
d = 7 . . . . . . . . divide by 9
y = 4d = 28 . . . . Yolanda's current age
y-d = 21 . . . . . . . Zachary's current age
Answer:
-2
Step-by-step explanation:
slope is rise over run
-2/1
= -2
Answer:
It is a little hard to see where your steps are for the equation, but x = 4, and I will explain:
Step-by-step explanation:
We know y = -1.5x +4, so we plug that into the equation
6x - 5(-1.5 + 4) = 34
6x +7.5x - 20 = 34 Here we distributed the -5 into the parenthesis.
13.5x -20 = 34
13.5 = 54
x = 4
Hope this helps!
I am not very sure about my answer but I will try my bes.
I think you earn 3% of $1200 every year for 5 years.
so 1200 divided by 100 is 12 which is 1% of 1200
12 multiplied by 3 is 36.
so 3% of $1200 is $36.
multiplied by 5 is $180.
you earn $180 interrs over 5 years with an interest rate of 3% from $1200
If the interest rate was increased by 1%, then you will earn a total of 4% interest.
4% of $1200 is 12 times 4 = $48
over 5 years, earning 4% of interest rate, you will earn a total of $240 interest.
If the interest rate is 3%, then over 5 years you will earn $180.
If the interest rate is 4%, then over 5 years you will earn $240.
If the year was increased by 1 then you will earn $36 × 6 dollars which is $216 with a 3% interest rate.
If the year was increased by 1 then you will earn 48 × 6 dollars which is $288 with a 4% interet rate.
X=40 degrees and y=40 degrees
