Answer:
8a=32
Step by Step
Since David is 8x older than Nicole you could write Nicole as the age of a, so then David would be 8a. You are given David is 32 years old so you set 8a equal to 32.
Answer is 4
Nicole is 4 years old
8a=32
divide both sides by 8
Answer is 4
The expression (2 x 7) x 3 represents the number of times Brandon went to the beach each week during 3 months. Which property is applied to write the equivalent expression 2 x (7x 3)? A. Distributive Property B. Commutative Property of Addition C.Associative Property of Multiplication D.Identity Property of Multiplication
Answer:
B. Distributive property
Step-by-step explanation:
Because (2 times 7) times 3 is the same as 2 times (7 times 3)
The numbers are just put different, and makes a different answer.
So, just because the answers are the same, doesn't make them commutative property,
So, the answer is B. Distributive propertySolve for the value of m.
(4m-5)
(3m+3)
Answer:
put the value m=1/2
3m(4m+5)=3
⇒3×1/2(4×1/2+5)+3
⇒3/2(2+5)+3
⇒6/2+15/2+3
⇒37 ans.
Step-by-step explanation:
For the equation, (4m-5)(3m+3)=37 value of m are 2.21 and -1.96
Equation consist of 2 expression equivalent to each other.
Given the following equation:
(4m-5)(3m+3)=37
To calculate the value of m as follows:
4m(3m+3)-5(3m+3)=37
12m²+12m-15m-15=37
12m²-3m-52=0.................................m)
Using discriminant formula:
[tex]d=b^2-4ac.............................1\\x=\dfrac{-b\pm\sqrt d}{2a}............................2[/tex]
Here, from equation m)
a=12, b=-3, c=-52
Substituting in equation 1
d=(-3)²-4(12)(-52)
d=2505
√d=50.04
[tex]m=\dfrac{3\pm 50.04}{2\times 12}\\\\m=2.21 \text{\ and\ } m=-1.96[/tex]
Thus value of m are 2.21 and -1.96

Which graph shows equivalent ratios?
A. On a coordinate plane, a line goes through points (2, 3) and (4, 4).
B. On a coordinate plane, a line goes through points (2, 2) and (3, 6).
C. On a coordinate plane, a line goes through points (1, 2) and (2, 4).
D. On a coordinate plane, a line goes through points (0, 6) and (1, 5).
Answer:
D
Step-by-step explanation:
It is because you can see the line pass through the value 0 in x-axis while 6 in y-axis which gives the first coordinate (x,y) = (0,6) and the line also past through the value of 5 in x-axis and 1 in y-axis which gives the second coordinate is (1,5).
So it is true that the line did go through at points (0,6) and (1,5).

this is the answer because Find the least common denominator or LCM of the two denominators:
LCM of 3 and 8 is 24
Next, find the equivalent fraction of both fractional numbers with denominator 24
For the 1st fraction, since 3 × 8 = 24,
1/3 = 1/3 × 3/8 = 8/24
Likewise, for the 2nd fraction, since 8 × 3 = 24,
3/8 = 3/8 × 1/3= 9/24
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
8/24 < 9/24
or 1/3 < 3/8

Hi there!
[tex]\large\boxed{3 \text{ boxes}}[/tex]
Calculate the number of boxes of cubes needed by calculating the volume of the pictured figure.
We can see that it has a width of 4 blocks, depth of 2 blocks, and a height of 8 blocks.
Calculate volume: V = l × w × h
V = 4 × 2 × 8 = 64 cubes in each box.
Since she needs 140 cubes, we can find how many boxes she would need for this amount:
140 ÷ 64 = 2.1875.
However, you cannot buy a part of a box, which is why you must round to a whole number. However, only buying 2 boxes would be too little.
Thus, she would need to buy 3 boxes.
What are the solutions to the equation: (x - 6)(x + 5) = 0?
answers
5
-5
6
-6
no joke answers or will be reported
Answer:
Step-by-step explanation:
Multiplying anything by zero equals zero. So if either term equals zero the equation is true.
(x-6)(x+5)=0
So if x=-5 or 6 the above is true.
x=(-5,6)
Answer:
the answers I found are 6 and -5
if you separate the two and equate them to 0 you will get the answers like this :
x - 6 = 0. or x + 5 = 0
x= 6. or x = -5
