Answer:
44 years old
Step-by-step explanation:
Let the age of Jasper be j years old now.
<u>Now</u><u>:</u>
Jasper➣ j
Simon ➣ j/2
<u>1</u><u>2</u><u> </u><u>years</u><u> </u><u>ago</u><u>:</u>
Jasper➣ j -12
Simon➣ j/2 -12
Given that Simon's age=⅕(Jasper's age),
j/2 -12= ⅕(j -12)
<em>Multiply</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>,</em>
2.5j -60= j -12
2.5j -j= 60 -12
<em>Simplify</em><em>:</em>
1.5j= 48
<em>÷</em><em>1.5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
j= 48 ÷1.5
<em>Simplify:</em>
j= 32
<u>12 years time:</u>
Jasper➣ j +12
Thus, Jasper's age
= 32 +12
= 44
Answer:
61
Step-by-step explanation:
(x2-x1)2 + (y2-y1)2
(5-0)2 + (-3-3)2
25+36= 61
square root of 61
Hello,
a)
the gradient is the slope:
y+2=3(x-0) or y=3x-2
b) slope is -5 (parallele to y=-5x+4)
y+1=-5(x-0) or y=-5x-1
Area = Length * Width
A = 2/5 * 3/5
A = 6/25 in2
In short, Your Answer would be Option B
Hope this helps!
Answer:
The students mistake was that he took 31% of the new price and added it to the new price. He should have taken 69% of his new price and added it to his new price. The original price was $375.36
Step-by-step explanation:
Lets work it out and compare our work. Since its 31% off, the formula we need to use is original times percent off equals the new price. Let x equal the original.
x*.69=259
Divide both sides by .69
(x*.69)/.69=259/.69
Divide
x=375.36
The original price was $375.36
The students mistake was that he took 31% of the new price and added it to the new price. He should have taken 69% of his new price and added it to his new price.
