Answer:
Step-by-step explanation:
the correct answer is 4x10^16
8x10^6 times 5 x 10^9
= 40 x 10^15
= 4 x 10^16
there is 40 which is 4 x 10, which you can add to the 10^15 to become 10^16
Answer:
40
Step-by-step explanation:
Natural numbers are numbers that occur commonly in nature and are whole non-negative numbers. Therefore, there are 40 natural numbers between 80 and 120.
Step-by-step explanation:
Let's solve your equation step-by-step.
3(2x+1)+4=10
Step 1: Simplify both sides of the equation.
3(2x+1)+4=10
(3)(2x)+(3)(1)+4=10(Distribute)
6x+3+4=10
(6x)+(3+4)=10(Combine Like Terms)
6x+7=10
6x+7=10
Step 2: Subtract 7 from both sides.
6x+7−7=10−7
6x=3
Step 3: Divide both sides by 6.
6x/6=3/6
x=1/2
Answer:
x=1/2
So you know that the area is greater than or equal to 60. Since 1/2 b x h is area, .5 x 12 x height (c) is greater than or equal to 60. Then solve, so .5 x 12 is 6, so 6c is greater than or equal to 60. then divide both sides by 6 and you end up with c is greater than or equal to 10
Answer:
(1, 4 )
Step-by-step explanation:
- 9x + 4y = 7 → (1)
- 2x - 4y = - 18 → 2)
add (1) and (2) term by term to eliminate y
- 11x + 0 = - 11
- 11x = - 11 ( divide both sides by - 11 )
x = 1
substitute x = 1 into either of the 2 equations and solve for y
substituting into (1)
- 9(1) + 4y = 7
- 9 + 4y = 7 ( add 9 to both sides )
4y = 16 ( divide both sides by 4 )
y = 4
solution is (1, 4 )
