Answer:
x=4.2
Step-by-step explanation:
7.8x = 32.76
/7.8 /7.8
x=4.2
In this sequence d=10. Therefore, a24=188.
Answer:
6 and 9
Step-by-step explanation:
set up an equation and solve for x
(x+3) * x = 54
easiest way to to try some numbers.
if you know your multiplication tables...
what two number multiplied together are 54
be sure the numbers you are thinking of meet the rules
is one 3 more than the other
do they multiply together to get 54
Answer:
V = 9.828 * 10^7 mm^3
a= 9.828 b = 7
9,827,000 mm^3
Step-by-step explanation:
The volume of a rectangular prism is
V = l*w*h
V = 1.2 *10^3 * 3.9*10^2 * 2.1*10^2
We multiply the numbers out front and add the exponents (the powers of 10)
V = (1.2*3.9*2.1) * 10^(3+2+2)
V = 9.828 * 10^7 mm^3
Rewriting this in standard form means moving the decimal 7 places to the left. Since there is not enough places add zeros
9,827,000 mm^3
Answer:
3
Step-by-step explanation:
39 ÷ (2+1) - 2 × (4+1)
Using BODMAS Rule,
= 39 ÷ 3 - 2 × 5
= 13 - 2 × 5
= 13 - 10
= 3
