So he has $40 in the bank. So first he buys gas for $40 , then writes a check for 64.75. So it would be 40-40-64.75= -64.75
Answer:
BC = 20
Step-by-step explanation:
AC = AB + BC
28 = x-10 + x+2
Combine like terms
28 = 2x -8
Add 8 to each side
28+8 = 2x-8+8
36 = 2x
Divide by 2
36/2 = 2x/2
18 =x
We want to find BC
BC = x+2
=18+2
=20

Hi Friend,
Solution is as follows!
Pupils in ROSE SCHOOL = 2185
GIVEN THAT,
there are 307 people more in lily school
HENCE,
people in LILY school will be = 2180 + 307 =<span>2487.
</span>
ROUNDING OFF TO NEAREST 10 we get
<span>2490.
</span>____________________________________________________________
(ii)TOTAL NUMBER OF PUPIL IN BOTH ROSE AND LILY SCHOOL=
2185+2487=<u><em>4672</em></u>
ROUNDING OFF TO nearest 100 we get
<u>2500
</u>
HOPE THIS HELPS!!!
So, you have to have your equation in terms of dimes. What you said about what he has: four more nickels than dimes in his pocket. Will help with our equation.
We know what a nickel and dime is worth. A nickel is .05 and a dime is .1
We don't know how many dimes are in his pocket, since we're trying to solve it.
.1x+(4+x).05=1.25;
In the parenthesis, it shows how there are four more nickels. Let's solve it now.
.1x + (4+x).05=1.25
.1x + .2+ .05x = 1.25; Let's add like terms.
.15x + .2 = 1.25; Subtract .2 from both sides.
.15x= 1.05
1.05÷.15= 7 =x
There are 7 dimes in his pocket, let's check our answer.
We now know there are 11 nickels, since there are four more nickels than dimes.
11(.05) +.1(7) = 1.25
.55+ .7 = 1.25
Now that we've tried it, we know there are 7 dimes in his pocket.
Tell me if this helps!
