Which of the following does not have 90 as a multiple?
7
6
5
3
Answer:
7
Step-by-step explanation:
I don't completely understand what you were asking, but if you were counting by 7's, 91 would be after 84 instead of just 90.
Answer:
7
Step-by-step explanation:
7x14=91, so 1 is not a multiple of 90. Don't really understand tho, plz comment if this is not what you meant.

7a + 50 = 247
Answer:
a = 28.14 (Estimated)
Step-by-step explanation:
7a + 50 = 247
=> 7a = 197
=> a = 28.1428571429 (Using Calculator)
=> a = 28.14 (Estimated)
Hoped this helped.
Answer:
a= 190
Step-by-step explanation:
7a+50=247
=7a = 247-50
= a = 197-7
= a = 190

Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?
Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
Answer
50 mph
Step-by-step explanation:
3(s-10)=2(s+10)
3s-30=2s+20
s=50
RectangleA′B′C′D′ is the image of rectangleABCD after a dilation.
What is the scale factor of the dilation?
The length of the side of the original is 3 units.
The length of the side of the smaller one is 1.5
Scale = 1/2
Select the expressions that are equivalent to 9d+4d.
Answer:
The first one, second one, and the last one. not the third one because 9d+3d=12d not 13d
Step-by-step explanation:
A right triangle has sides of length 3, 4, and x. Find x if it is the hypotenuse.
HELP ME PLEASE
Answer:
5
Step-by-step explanation:
The rules for the hypotenuse is side a^2+side b^2=hypotenuse^2
a=3
b=4
3^2=9
4^2=16
9+16=25
5^2=25, so 5 is the hypotenuse.

Graph the solution to this inequality on the number line. −1/3x + 1/2 ≥ −3/4
Answer:
4.5 (4.5 units to the left of 0) Make sure to draw a solid dot over 4.5 and an arrow pointing in the right direction.
>= is the greater than or equal to symbol
Step-by-step explanation
1. Combine like terms- In this problem, the like terms are 1/2 and -3/4, so to move 1/2 over to the other side of the equation, we have to divide each side by 2/1, which is the same as multiplying each side by 2: -1/3x + 1/2 * 2 >= -3/4 * 2.
2. Separate the fraction from x- Now, we simply divide each side by -3/1, which is the same as multiplying each side as -3: -1/3x * -3 >= -3/2 * -3
3. Graph on the number line- We've found that x = 4.5. To check, substitute in 4.5 for the value of x: -1/3(4.5) + 1/2 >= -3/4. -1 >= -3/4 is a true inequality. To graph it on the number line, draw a solid dot over 4.5 and an arrow in the direction of the righthand side.

which does not represent two equivalent expressions 51 MAFS.6.EE.1.1 Which does not represent two equivalent expressions?
A.) 33=3·3·3
B.) 43=4·3
C.) 64=6·6·6·6
D.) 52=5·5
Answer: B
Explanation: 4 times 3 is equivalent to 12 and the question was asking for exponents. A has 3 multiplied by itself 3 times so that is correct. C has 6 multiplying itself 4 times so that would be correct. D has 5 Multiplying itself 2 times so that would be correct. The only one that does not represent equivalency would be B.
