At the toy store, Caleb and his younger brother, Gabe, each used money they had saved to buy Motor Mystery boxes. The convertibles are their favorite cars to get! Out of the 30 cars in Caleb's Jumbo box, 12 were convertibles. Out of the 10 cars in Gabe's Mini box, 4 were convertibles. Did the boxes have the same ratio of convertibles to total cars yes or no
Answer:
Answer: Yes
Step-by-step explanation:
Ratios
Caleb's Jumbo box has 30 cars, 12 of which are convertibles.
This gives a ratio of 12:30. The equivalent fraction of this ratio is:
[tex]\frac{12}{30}[/tex]
This fraction can be simplified by dividing both parts by 6:
[tex]\frac{2}{5}[/tex]
Thus Caleb's ratio of convertibles is 2:5.
Gabe's Mini box has 4 convertibles out of 10 cars. This gives a ratio of 4:10.
Simplifying by 2, the ratio is 2:5.
It's clear that both boxes have the same ratio of convertibles to total cars.

Jan and Kim own numbers of marbles
that are in the ratio 5:6
Jan gains 2 more marbles and the ratio is
now 7:8
how many marbles do each own initially?
Answer:
5:6 + 7:8 = 12:14
Jan will have 12 marbles
Kim will have 14 marbles
Jan and Kim own 40 and 48 marbles respectively.
Important information:
Jan and Kim has marbles in ratio 5:6.Jan gains 2 more marbles and the ratio is 7:8.We need to find the initial number of marbles each own.
Ratio:Let the initial number of marbles be [tex]5x[/tex] and [tex]6x[/tex].
Jan gains 2 more marbles and the ratio is 7:8. So,
[tex]\dfrac{5x+2}{6x}=\dfrac{7}{8}[/tex]
[tex]8(5x+2)=7(6x)[/tex]
[tex]40x+16=42x[/tex]
Isolate the variable.
[tex]16=42x-40x[/tex]
[tex]16=2x[/tex]
[tex]\dfrac{16}{2}=x[/tex]
[tex]8=x[/tex]
Now, find the initial number of marbles.
[tex]5(8)=40[/tex]
[tex]6(8)=48[/tex]
Therefore, Jan and Kim own 40 and 48 marbles respectively.

Which value could you write in the blank above that would make the equation have one solution?
a.2x
b.8
c.7
Answer:
2x
Step-by-step explanation:
Think about it. Adding 8 would make the equation: 3x+8=3x+8. That has infinite solutions. if you made it 7, it would be 3x+8=3x+7, which is impossible.
Therefore, it must be 2x, which would make the equation 3x+8=5x.
Let's check: 3x+8=5x
8=2x
4=x

If y varies directly with x, given x = 4 and y = 8. What is the value of k (constant of proportionality)?
Answer:
2Step-by-step explanation:
If y y varies directly with x, this is expressed as;
y ∝ x
y = kx
k is the constant of proportionality;
Given
x = 4 and y = 8
Substitute;
8 = 4k
4k = 8
k = 8/4
k = 2
Hence the constant of proportionality k is 2
