Answer: y=-4
Step-by-step explanation:
8(3)+5y=4
24+5y=4
subtract each side by 24
5y=-20
divide by 5
5 y=-4
All you have to do is:
Make all of your fractions to common denominator.
Then, you add 8 3/10-1 2/5- 2 1/3+ 4 3/5
And when you solve it, you get 9 5/30 and when you simplify it,
You get 9 1/6 yards of ribbon
Use algebra.
Let the number of stickers each had in the beginning = x stickers.
Ray lost 10 we represent this by
x - 10 ( = no. stickers he has now)
Tom bought 200 so the number of stickers he now has
= x + 200
Rays has 1/4 as much as Tom so we can now create the equation
1/4(x + 200) = x - 10
Soling for x:-
1/4 x + 50 = x - 10
60 = 3/4 x
x = 60 * 4/3 = 80
Answer they had 80 stickers at first.
Answer:
x = 7
y = 8
Step-by-step explanation:
Since the shapes are similar then <B = <F and <A = <E
<B = <F so
10x + 65 = 135 subtract 65 from both sides
10x = 70 divide both sides by 10
x = 7
<A = <E so
4y - 4 = 28 add 4 to both sides
4y = 32 divide both sides by 4
y = 8
