Answer:
-2.8h-26+5d
Step-by-step explanation:
So just combine like terms
For the h, you’d get -2.8
For the d, you’d get 5
For the normal integer, -26
Answer:
8h-7.9d-16+5d-2.9h
5.1h-7.9d-16+5d
=5.1h-2.9d-16

1. John’s age is three times that of his sister. When you add John’s age to his sister's age, you get 36. How old are John and his sister?
(a) Write an equation that represents the situation. (1 point)
(b) Solve the equation from Part (a). Show your work. (3 points)
Answer:
Part A: Write an equation.
If the present age is y, then n times the present age = ny.
If the present age is x, then age n years later/hence = x + n.
If the present age is x, then age n years ago = x – n.
The ages in a ratio a: b will be ax and bx.
Part B: Solve the equation.
John’s age =
John’s sister’s age =
Answer:
sister = 6 years
John=18 years
Step-by-step explanation:
A(S) + 12 = 3 * A(S), subtracting A(S) from both sides one gets 12 = 2 * A(S). Now dividing both sides by 2 we get A(S) = 12/2 = 6 . Therefore, the age of the sister is 6 years when her brother John is three times as old, that is 18 years.
Answer:
36-x=y
y*3=x
x+y=36
Step-by-step explanation:
I wasnt really sure how to write the equation the way you're supposesd to?
John is 27 and his sister is 9. 9*3=27

question:
Sonia has two packages of hamburger meat. The first package weighs 1.76 pounds and the second package weighs 2.29 pounds. She mixed the two packages together and forms hamburgers that weigh 0.25 pounds each. What is the greatest number of 0.25-pound hamburgers Sonia can make using the hamburger meat she has?
Answer:
16
Step-by-step explanation:
2.29+1.76=4.05
4.05/0.25=16.2
round down to 16
you would have a little extra but you would only be able to make 16 .25 pound ones
A.45
B.25
C.118
D.93
Answer: A
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+3)+25=3x-17 [combine like terms]
2x+28=3x-17 [subtract both sides by 2x]
28=x-17 [add both sides by 17]
x=45
Now, we know that the answer is A.

SOMEONE PLEASE HELP ME WITH THIS!!!!! ITS GEOMETRY
Answer:
KG = 7 (A)
m KIH = 28 (B)
m JIH = 96 (D)
m HKI = 68 (B)
m KJI = 84 (C)
Step-by-step explanation:
Notice that the triangle HKJ is identical to HIJ. Since there are lines drawn to each other and both triangles are identical, the lines KG and GI are the same. This means that it is 7.
The triangle KGJ is identical with IGH. Using the recognise angle property, we know that angle JKI is the same as KHI. This means that it is 28.
Angle JIH is the same as angle JKH. Since JKH is 180 - (KHI or 84), we know that the angle JIH is 96.
We can find angle HKI by subtracting 96 by 28 because we know that angle HKI is the same as JIH. This gives us 96-2 8 = 68.
Angle KJI is the same as KHI which is 84. Therefore, KJI is also 84.
Solve this system of equations.

A Web music store offers two versions of a popular song. The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.1
MB. Yesterday, there were 1600 downloads of the song, for a total download size of 5624 MB. How many downloads of the high-quality version were
there?
Number of high-quality version downloads:
Answer:
Number of high quality version downloads = 880
Step-by-step explanation:
Let,
x be the number of standard version songs downloaded
y be the number of high quality version songs downloaded
According to given statement,
x+y=1600 Eqn 1
2.8x+4.1y=5624 Eqn 2
Multiplying Eqn 1 by 2.8 to eliminate x
2.8(x+y=1600)
2.8x+2.8y=4480 Eqn 3
Subtracting Eqn 3 from Eqn 2
(2.8x+4.1y)-(2.8x+2.8y)=5624-4480
2.8x+4.1y-2.8x-2.8y=1144
1.3y=1144
Dividing both sides by 1.3
[tex]\frac{1.3y}{1.3}=\frac{1144}{1.3}\\y=880[/tex]
Hence,
Number of high quality version downloads = 880
Ray Barbee, a radio announcer, is single, earns $300.74 weekly, and claims 2 allowances.

Which equation is NOT written in slope-intercept form?
Answer and Explanation
__________________________________________________________
B) 2x - 5 = 2y + 14
__________________________________________________________
slope intercept form: y = mx + b

What is the answer ???????????????
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x - 9 → (1)
y = x - 3 → (2)
Substitute y = 4x - 9 into (2)
4x - 9 = x - 3 ( subtract x from both sides )
3x - 9 = - 3 ( add 9 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations for y
Substituting into (2)
y = 2 - 3 = - 1
solution is (2, - 1 )

0.3x – 2.7 =T0-0)
Step-by-step explanation:
0.3x = (0.3)(x).
2.7 = (0.3)(9).
Between the 2 terms, the GCF is 0.3.
Hence,
0.3x - 2.7
= (0.3)(x) - (0.3)(9)
= 0.3(x - 9).
