Answer:
No. it would be 4 3/14
Step-by-step explanation:
5-1=4
common denominator is 14 to get there,
1x7=7
2x7=14
2x2=4
7x2=14
7/14 - 4/14 = 3/14
put it all back together and you get 4 3/14
Answer:
3
Step-by-step explanation:
mhm for your brother
anyways...
2x-3+6x = 21
Adding like terms
8x -3 = 21
Adding 3 on both sides
8x = 24
Dividing both sides by 8
x = 3
Answer:
Step-by-step explanation:
1.) 700*0.42 = 294. Out of the 700 people at the concert, 294 are tennagers.
2.) 1.07*$450 = $481.50, including sales tax (final price)
3.) 120/(100%-85%) = 120/0.15 = 800. Original amount of water is 800 ml (Check by 800mL*0.15, which equals 120 mL)
4.) 100-35-45 = 20%
250*20% = 50; Out of the 250 sandwiches, Josh made 50 ham sandwiches.
Answer:
see below
Step-by-step explanation:
slope intercept form: y=mx+b
you are given the slope, and can plug the points in to find b.
a) -3=2/3(6)+b --> b=-7
y=2/3x+7
b)10=-8(1/2)+b --> b=14
y=1/2x+13
c)4=-3(2)+b --> b=10
y=-3x+10
Father = x
son = y
x-5 = 7(y-5)
x +5 = 3(y+5) solve the system
x-5 = 7y-35
x+5 = 3y +15
x-5 = 7y-35
-x-5 = -3y -15
-10 = 4y -50
+50 +50
40 = 4y
10 = y
Solve for X
x+5 = 3(10) + 15
x+5 = 45
x = 40
The father is 40yrs old and the son is 10yrs old.
