Joe has $20 to spend on two model cars and supplies to paint them. The paint supplies cost $4.00 Which expression shows how much he can spend on each model?
A. x ≤ $8
B. x ≥ $8
C. x ≤ $16
D. x ≥ $16
Answer:
So he has 20$ to spend. He spends 4$ to paint them. That means that after getting the supplies he would have 16$ left to spend on the cars.
Answer:
A. x ≤ $8Step-by-step explanation:
John has $20He spends $4 on paint suppliesHe can spend x dollars on each model and 2x on both:
2x ≤ 20 - 42x ≤ 16x ≤ 8Correct choice is A.

sam writes on a white board the positive integers from 1 to 6 inclusive once each. she then writes p additional fives and q sevens on the board. The mean of all the numbers on the board is then 5.3. What is the smallest possible value of q?
Answer:7
Step-by-step explanation:
This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....
Also the 3 has a recurring symbol above it
The 7 is times seven so uh yeah<3
The smallest possible value of 'q' is 7 and this can be determined by using the hit and trial method and mean formula.
Given :
Sam writes on a whiteboard the positive integers from 1 to 6 inclusive once each. she then writes p additional fives and q sevens on the board.The mean of all the numbers on the board is then 5.3.The following steps can be used in order to determine the smallest possible value of q:
Step 1 - The formula of the mean can be used in order to determine the smallest possible value of q.
Step 2 - The mean of all the numbers is given by:
[tex]\rm \dfrac{2+4+6+5+5p+7q}{6+p+q}=5.3[/tex]
[tex]\rm \dfrac{21 + 5p + 7 q}{6+p+q} = 5.3[/tex]
Step 3 - So, by the hit and trial method, the value of q can be determined.
Therefore, the value of 'q' is 7.

Answer:
both x angles are equal to 40 degrees
Answer:
x would equal 40
Step-by-step explanation:
a line is 180, the angle inside the triangle is 100 and x is on both sides that means x would equal 40 because there is 2 x's and 100 is already a number and 180 is a line.
180 = x + x + 100
x + x + 100 - 100 = 180 - 100
x + x = 80
2x = 80
2 ÷ 2x = 80 ÷ 2
x = 40

A bag contains 4 green marbles, 3 red marbles, and 7
blue marbles. One marble is taken from the bag and put
back after checking its color. A second marble is then
taken out. What is the probability that the first is blue
and the second red?
Answer:
3/28
Step-by-step explanation:
There are 14 marbles in the bag. So, the probability of choosing a blue marble is 7/14 or 1/2. Since the first marble is replaced, the bag still has 14 marbles in it. Then the probability of choosing a red marble is 3/14. The probability of choosing the blue, then the red is 1/2 x 3/14 = 3/28

Step-by-step explanation:
What is the point-slope form of a line with a slope -3 that contains the point (10,-1)
Here's the formula:
y - y1 = m(x - x1)
Substitute numbers accordingly:
y1: so 1 goes in the y1 spot (you switch the signs because it was already negative)
x1: and 10 goes to the x1 spot
m: -3 belongs in m
In the group of ordered pairs shown, the x-values are inputs and the y-values are outputs. Which statements are true about the inputs and outputs?
Select all that apply
(2, 4), (6, 3), (5, 4). (7,3), (8.2)
A There is only one input for every output.
B. There is only one output for every input.
C. There is more than one output for some inputs.
D. There is more than one input for some outputs.

What is 38 percent of 10 oranges
Answer:
The answer is 3.8
Explanation:
Move the decimal over once to the left.
Answer:
3.8 oranges.
Step-by-step explanation:
Step 1: Our output value is 10.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 10=100%.
Step 4: Similarly, x=38%.
Step 5: This results in a pair of simple equations:
10=100%(1).
x=38%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
10/x= 100%/38%
Step 7: Again, the reciprocal of both sides gives
x/10 = 38/100
---> x=3.8$
Therefore, 38% of 10 is 3.8

A jar mung beans and lima beans in a ratio of 2 : 3, and 120 of the beans are mung beans. How many beans in total are there in the jar?
Answer:
300
Step-by-step explanation:
2 : 3
120/2=60
1 part = 60
(60 x 2) + (60 x 3) = 300 total
There is a total of 300 beans in the jar mung.
What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.
We have been given a jar of mung beans and lima beans in a ratio of 2 : 3, and 120 of the beans are mung beans.
So, 2 : 3
1 part, 120/2 = 60
The total beans in the jar,
(60 x 2) + (60 x 3) = 300
Hence, there is total of 300 beans in the jar.
