Answer:
Step-by-step explanation:
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
200 = 0.5 × 5x × 5x
→ Simplify
200 = 12.5x²
→ Divide both sides by 12.5
16 = x²
→ Square root both sides
4 = x ∴ x = 4
Answer:
(-5.77, 6.46)
Step-by-step explanation:
15x + 9y = 45 ----------- i
9x + 8y = 12----------------ii
Multiply equation i by 9 the coefficient of x in equ ii
And equation ii by 15 the coefficient of x in equ I
9 x 15x + 9y = 45 ----------- i
15 x 9x + 8y = 12----------------ii
135x+81y = 405
135x+120y= 180
Subtract equation ii from I
135x-135x+81y-(+120y)= 405-180
-39y=225
y = 225/-39 = -5.77
Insert the value of y in equ i
15x + 9y = 45
15x+9(-5.77) = 45
15x-51.92=45
15x = 45+51.92
15x= 96.92
x = 96.92/15= 6.46
(x,y) = (-5.77, 6.46)
x = 6.92/15
Answer:
s is equal to 2
Step-by-step explanation:
Answer:
The slope is 2.
Step-by-step explanation:
You can see on the intercepts that it goes rise 2 and run over 1 which would basically equal to 2.
This is a simple subtraction problem, but since you are in Elementary School, I will help you out.
Subtract $4,190.67 by $3,655.11 (remember, the bigger number should come first)
4,190.67
<span>-3,655.11
</span> ...56
When a small number is on top of a bigger number, borrow 1 number from the number next to it (in this case, 0 is smaller than 5, so you must borrow 1 number from 9, making it to 8), then add the small number by 10 (0+0=10)
<span>Then we continue...
</span> 4,190.67
<span>-3,655.11
</span> 35.56
Do the same thing with 4 and 1.
4,190.67
<u>-3,655.11</u>
535.56
<em><u>Answer: $535.56</u></em>
