Answer:
The x-intercept is -2
Step-by-step explanation:
Answer:
9, 7,-8.3,>
Step-by-step explanation:
5)-3 is marked exactly 3 units to the left of origin 0.
(since negative sign we mark on left of 0)
6) |-9| = absolute value of 9 = 9
7) y-11=-4
Add 11 to both the sides
WE get y =7 is the solution
8) a + b when a = 2.5 and b = -10.8.
= 2.5+(-10.8) = -(10.8-2.5) = -8.3
9) 0.4 is positive hence lies to the right of origin.
Partition the space between 0 and 1 into 10 equal subparts and mark 4th subdivision to get 0.4
10) -1.8>-2.5
Answer:D
Step-by-step explanation:9*3=27
27+25=52
Answer:
2.1 * 10 ^3
Step-by-step explanation:
5.67 * 10 ^7 ÷2.7 x 10^4
Divide the numbers
5.67 / 2.7 =2.1
Divide the exponents
10^7 / 10 ^4
Remember when dividing power, we subtract the exponents
10 ^(7-4) = 10^3
Put this back together
2.1 * 10 ^3
Verify that this is in scientific notation
Since this is in scientific notation, we are done
-14 = -5 + 3c
First, regroup your terms. / Your problem should look like:
Second, add 5 to both sides. / Your problem should look like:
Third, simplify -14 + 5 to -9. / Your problem should look like:
Fourth, divide both sides by 3. / Your problem should look like:
Fifth, simplify the fraction to 3. / Your problem should look like:
Sixth, switch your sides. / Your problem should look like:

Answer:
c = -3
