Answer: ok ima try my best
the numbers that's in the {} are the umbers you put in for x so
10+10=22 is false
12+10=22 is true
in the x columns you put in the numbers
in the columns with the (x+10=22) you input the number for x so just rewrite it
then you answer if its the answer or not
Step-by-step explanation:
10+10=22 is false
12+10=22 is true < this one is the only one that's true the rest are false
i hope this helps
Answer:
12.8 so answer 12 or 13
Step-by-step explanation:
15÷5/8= 12.8
The mean basically means the average number between all numbers given. You can find the mean by adding them together and diving by the number of numbers. In this case, 12 + 24 + 24 + 52= 112. Divide 112 by 4 and the answer is 28. Therefore, the mean is 28.
As aforementioned, the volume is just the product of the dimensions, you have all three, just get their product.
now for the area, check the picture below.
notice the prism, container, is really just 6 rectangles stacked up to each other at the edges.
front and back, two 2.5x3.7
left and right, two 2.5x5.2
top and bottom, two 5.2x3.7
so we just get the area of all 6, sum them up, and that's the area of the prism.
Answer:
19a.) 6x-1=4 --> 6x=5 --> x=5/6
b.) 4w+3=10 --> 4w=7 --> w=7/4
Evaluate when t= -2
20a.) 5t-3 --> 5(-2)-3= -10-3= -13
b) the sequence 5+t, 5+2t, 5+3t, 5+4t. = 3, 1, -1, -3
c.) 18- t² =18-(-2)^2= 18-4=14
20d) the sequence 2t- 3, 2t-5, 2t-7, 2t-9. = -7, -9, -11, -13
21.) Find the value of these expressions when p=2, q=3 and r=6
21 a)5q = 5(3)=15
b) p+q
= 2+3= 5
c) qr
= 3*6= 18
d) 2p+ 3q
= 2(2)+3(3)=4+9= 13
e) r² = 6^2=36
