one number is equal to 4 times another number. their difference is 12. find the numbers
Answer:
[tex]x=16 \ \ and \ \ y=4[/tex]
Step-by-step explanation:
Suppose the numbers are x and y
One number say x is equal to 4 times another number say y
[tex]x=4y[/tex] ---------------- (1)
Their difference is 12
[tex]x-y=12[/tex] ------------(2)
Put x=4y in equation (2)
[tex]4y-y=12[/tex]
[tex]3y=12\\y=4[/tex]
Put y=4 in equation (1)
[tex]x=4(4)\\x=16[/tex]
Find a and b. Help me please.

Lee buys h packs of hotdogs and b packs of buns for a party. Hotdogs come in
packs of 8 and buns come in packs of 12. Write an expression for the total number
of hotdogs and buns bought, in terms of h and b.
Answer:
8h + 12b
Step-by-step explanation:
Given that:
h = Hotdog packs
b = pack of buns
Hotdogs are packed in 8
Buns are packed in 12
The total number of hotdogs and buns bought expressed in terms of h and b is :
(Number of hotdog packs * number per pack) + (Number of buns pack * number per pack) =Total number of hotdog and buns
8h + 12b

Addition property of equality
+(-)=k+1+(-)
Answer:
[tex]k = -4[/tex]
Step-by-step explanation:
Given
[tex]\frac{3}{2} = k + \frac{11}{2}[/tex]
Required
Solve for k
[tex]\frac{3}{2} = k + \frac{11}{2}[/tex]
Apply subtraction property
[tex]\frac{3}{2} - \frac{11}{2} = k + \frac{11}{2} - \frac{11}{2}[/tex]
Apply addition property
[tex]\frac{3}{2} +(- \frac{11}{2}) = k + \frac{11}{2} +(- \frac{11}{2} )[/tex]
The fractions on the right represent an additive inverse.
So, we have:
[tex]\frac{3}{2} +(- \frac{11}{2}) = k[/tex]
Take LCM
[tex]\frac{3+(-11)}{2} = k[/tex]
Remove bracket
[tex]\frac{3-11}{2} = k[/tex]
[tex]\frac{-8}{2} = k[/tex]
[tex]-\frac{8}{2} = k[/tex]
[tex]-4 = k[/tex]
[tex]k = -4[/tex]

may 3rd -> july 15th = 73 days
500*0.06 = 30
30 = how much he makes in one day (so he has 530 after 1 day)
30*73 = 2190
500 + 2190 = 2690
9.
210/7 = 30
1% for 3 years = 30
1% for 1 year = 10
100% for 1 year = 1000
2000*0.06 = 120
11.
54,000*0.08 = 4320
54,000/4320 = 12.5

What is the length of the Midsegment?
12
18
6
9
Answer:
The length of Midsegment = 9
Step-by-step explanation:
the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side.
According to the Midsegment Theorem:
The midsegment connects the midpoints of two sides of a triangle is parallel to the third side of the triangle.The length of this midsegment is half the length of the third side.Thus,
The midsegment (x+4) is half the length of the third side (4x-2). so
[tex]\left(x+4\right)\:=\:\frac{1}{2}\:\left(4x\:-\:2\right)[/tex]
[tex]x+4=2x-1[/tex]
Subtract 4 from both sides
[tex]x+4-4=2x-1-4[/tex]
[tex]x=2x-5[/tex]
Subtract 2x from both sides
[tex]x-2x=2x-5-2x[/tex]
Simplify
[tex]-x=-5[/tex]
divide both sides by -1
[tex]\frac{-x}{-1}=\frac{-5}{-1}[/tex]
Simplify
[tex]x=5[/tex]
As
The length of Midsegment = x+4
= (5) + 4 ∵ x = 5
= 9
Therefore, the length of Midsegment = 9

Subtract 2w + 4 from 3w + 6.
Answer:
w+2
Step-by-step explanation:
When subtracting when you have variables and constants, you combine like terms. subtract the 2w from the 3w, and the 4 from the 6. then you get 1w and 2. Put them together, and the equation is simplified to w+2.
