Answer:
4-3x=0
-3x=-4
x=4/3
tip:- it should always be equal to 0
Work:
The total is 179.50, if Abe has 9 more $ then do 179.50-9.00=170.50 then do 170.50-18.00 bc 3x9=18 and get 152.56
Answer: Belle has $152.56
Answer:
187
Step-by-step explanation:
A number m is such that when it is divided by 30, 36 and 45 the remainder is always 7.
We should first find the LCM of 30, 36 and 45
We get that the LCM of the three numbers is 280 (working attached).
So now;
= 6
= 5
= 4
But we need a number that leaves a remainder of 7 so we add 7 to 180 to get; 180 + 7 = 187.
Scores on one variable plotted against scores on a second variable.
The correct answer is (b)
Now, According to the question:
Let's know:
<u>A scatterplot shows:</u>
A scatterplot shows the relationship between two quantitative variables measured for the same individuals. The values of one variable appear on the horizontal axis, and the values of the other variable appear on the vertical axis. Each individual in the data appears as a point on the graph.
Hence, The correct answer is (b) i.e.,
Scores on one variable plotted against scores on a second variable.
Given,
In the question:
A scatterplot shows:
a. the average value of groups of data.
b. scores on one variable plotted against scores on a second variable.
c. the frequency with which values appear in the data
d. the proportion of data falling into different categories.

12) if x is 0, then it lies on the y-axis. If y is 0, then it lies on the x-axis.
a) (0, 4) lies on y-axis
b) (-2, 0) lies on x-axis
c) (3, 0) lies on x-axis
d) (0, -1) lies on y-axis
13) multiply each of them out and add them together. You will see that the first and last terms cancel, leaving you with the middle terms which each have a coefficient of 3.
3[xy(y - x) + yz(z - y) + xz(x - z)]
14) x³ - x
= x(x² - 1)
= x(x - 1)(x + 1)
15) Using synthetic division for 5x⁴ - x³ - 2x² + x + 9 ÷ x -

|<u> 0.5 2.75 0.875 0.5625 0.78125 </u>
5.5 1.75 1.125 1.5625 9.78125
Remainder is: 9.78125
16) TRUE. This is known as the Triangle Angle Sum Theorem
17) Separate into two triangles, use Heron's formula to calculate the area for each triangle, then find their sum.
ΔABC: s = (6 + 7 + 9)/2 = 11, A = √(11)(5)(4)(2) ≈ 21
ΔCDA: s = (12 + 15 + 9)/2 = 18, A = √(18)(6)(3)(9) ≈ 54
ΔABC + ΔCDA: 21 + 54 = 75 cm
18) 3√45 - √125 + √200 - √50
= 9√5 - 5√5 + 10√2 - 5√2
= 4√5 + 5√2
