Answer:
1a. 64=4(7+x)
1b. x=9
2a. 64=7+4x
2b. x=57/4
Step-by-step explanation:
1a. To represent this situation, all of the weight for each package must be in the equation. Since each package has 4 boxes, and only the objects in one box are detailed, everything must be multiplied by 4. Now, the values that must be multiplied by 4 are a bag of rice and beans. Since the beans weigh 7 pounds, they can be represented using the constant 7, and the rice can be represented with the variable x. Combining all of this information, the equation 64(total)=4(7+x)
1b. Now, the equation above must be solved. First, divide both sides by 4 in order to get 16=7+x. Now, subtract 7 from both sides to find that x=9
2a. This problem is similar to the first problem, except instead of multiplying both the beans and rice by four, only the rice needs to be multiplied. With this knowledge the equation 64=7+4x is created.
2b. To solve the above equation, 7 must be subtracted from both sides. This leaves 57=4x. Now, both sides must be divided by 4, giving the final answer of x=57/4.
Answer:
1a. 64=4(7+x)
1b. x=9
2a. 64=7+4x
2b. x=57/4

Answer:
2.68 × [tex]10^{26}[/tex] Km³
Step-by-step explanation:
Using the given formula for volume V, then
V = [tex]\frac{4}{3}[/tex] π × (4 × [tex]10^{8}[/tex] )³
= [tex]\frac{4}{3}[/tex] π × 4³ × ([tex]10^{8}[/tex] )³
= [tex]\frac{4}{3}[/tex] π × 64 × [tex]10^{24}[/tex]
= 268 × [tex]10^{24}[/tex]
= 2.68 × 10² × [tex]10^{24}[/tex]
= 2.68 × [tex]10^{26}[/tex] Km³

- 5x + 35 = 40 ( subtract 35 from both sides )
- 5x = 5 ( divide both sides by - 5 )
x = - 1
Rationalize the denominator and simplify. √a+1 - 2 / √a+1 + 2
Answer:
5+a-4√a+1 / a-3
The rationalization of given expression is a+5-4√(a+1)/(a+5).
What is Rationalization?Rationalization can be considered as the process used to eliminate a radical or an imaginary number from the denominator of an algebraic fraction. That is, remove the radicals in a fraction so that the denominator only contains a rational number.
The given expression is √(a+1)-2/√(a+1)+2.
Multiply both numerator and denominator by (a+1)-2, we get
√(a+1)-2×(a+1)-2/√(a+1)+2×(a+1)-2
= (√(a+1)-2)²/(√(a+1))²+2²
= (√(a+1))²-2×√(a+1)×2+2²/a+1+4
= a+1-4√(a+1)+4/(a+5)
= a+5-4√(a+1)/(a+5)
Therefore, the rationalization of given expression is a+5-4√(a+1)/(a+5).

The formula for the area of a trapezold with altitude k and bases m and n is A=k/2(m+n)
Solve for m.
Answer:
[tex]m=\frac{2A-kn}{k}[/tex]
Hence, option C is true.
Step-by-step explanation:
Given the expression
[tex]A=\frac{k}{2}\left(m+n\right)[/tex]
Solving for 'm'
[tex]A=\frac{k}{2}\left(m+n\right)[/tex]
Flip the equation
[tex]\frac{k}{2}\left(m+n\right)=A[/tex]
Expanding by applying the distributive law: [tex]a\left(b+c\right)=ab+ac[/tex]
[tex]\frac{1}{2}km+\frac{1}{2}kn=A[/tex]
Add (-1)/2 × kn to both sides
[tex]\frac{1}{2}km+\frac{1}{2}kn+\left(-\frac{1}{2}kn\right)=\left(-\frac{1}{2}kn\right)+A[/tex]
simplify
[tex]\frac{1}{2}km=-\frac{1}{2}kn+A[/tex]
Divide both sides by k/2
[tex]\frac{\frac{1}{2}km}{\frac{k}{2}}=\frac{-\frac{1}{2}kn+A}{\frac{k}{2}}[/tex]
[tex]m=\frac{2A-kn}{k}[/tex]
Therefore,
[tex]m=\frac{2A-kn}{k}[/tex]
Hence, option C is true.

Joe is 3 years less than twice as old as Sara. The sum of the ages of Joe and Sara is 42. If x represents Sara's age,
Answer:
Sara or x=15, Joe=27
Step-by-step explanation:
Using J to represent Joe and S to represent Sara
J=2S-3
J+S=42 or J=42-S
Substitute for J:
42-S=2S-3
3S=45
S=15
J=2(15)-3 = 27

Hooke’s Law of Elasticity states that the force applied, y, varies directly with the distance a spring stretches, x (assuming the spring is not stretched past its elastic limit). If a force of 160 newtons stretches a spring 800 cm, how far will a force of 368 newtons stretch the same spring? Justify your answer.
Group of answer choices
F. It will stretch the same spring 73.6 cm because the equation is y equals 5x.
G. It will stretch the same spring 73.6 cm because the equation is y equals one fifth x..
H. It will stretch the same spring 1,840 cm because the equation is y equals 5x.
J. It will stretch the same spring 1,840 cm because the equation is y equals one fifth x..
Answer:
H: It will stretch the same spring 1,840 cm because the equation is y equals 5x.
Step-by-step explanation:
800=y
160and368=x
You find the answer by dividing,
⁸⁰⁰⁄₁₆₀= ʸ⁄₃₆₈800 divided by 160 equals 5 which means the equation is y equals 5x
and 368x5=1,840

find the constant of proportionality (r) in the equation y=rx
Answer:
5
Step-by-step explanation:
The constant of proportionality (r) in the equation y=rx is 3
How to determine the constant of proportionality?The equation of the function is given as:
y = rx
Make r the subject
r = y/x
From the table, we have:
y = 36 when x = 12
So, the equation becomes
r = 36/12
Divide
r = 3
Hence, the constant of proportionality (r) in the equation y=rx is 3
