Answer:
x= -12
Step-by-step explanation:
Move the constant to the right
7x-6=-90
Calculate
7x=-90+6
Divide both sides by 7
7x=-84
Solution
x=-12
Paula : 13 4/9 = 13.44 seconds
Gina : 13 10/33 = 13.30 seconds
Jaime : 13.55 seconds
Gina ran the 100 meter dash in the least amount of time
The new statement will be:
- The nuclear power plants wastes are very toxic.
- Air pollution from Nuclear power plants is much lower that from power
- plants that make use of fossil fuels.
- Power plants that are Nuclear are regarded as safe.
- The risks of nuclear power is much more lower than the benefits.
<h3>What changed my mind in the above?</h3>
Nuclear energy is known to be one that produce a lot of radioactive waste and this tends to pose a threat to human health and the environment.
Hence, The new statement will be:
- The nuclear power plants wastes are very toxic.
- Air pollution from Nuclear power plants is much lower that from power
- plants that make use of fossil fuels.
- Power plants that are Nuclear are regarded as safe.
- The risks of nuclear power is much more lower than the benefits.

Because the average is 7.7, his total points are equal to 7.7*10=77.
Because 7*10<77<8*10, Luke cannot have scored 8 10s. We now seek to prove that he can score 7 tens.
This leaves him with three tests left, that sum to 7 marks. There are clearly many ways to arrange this - for example, 2, 3, and 3 on the first three tests, then ten on all seven other tests. As this shows that 7 10s works and we have proven that 8 10s does not work, 7 is the maximum amount of 10s Luke could have scored.
The change represents decay and the percentage decrease is 2.9%
<h3>Exponential function</h3>
The standard exponential function is expressed as y = ab^x
where:
a is the initial
b is the rate
If the value of b is less than 1 hence the function is decay and if greater than 1, the function is growth
GIven the expoenential function y=100(0.971)^x
Since the value of b = 0.971 < 1, hence the function is a decay.
The percentage decrease = 1 - 0.971 = 2.9%
Hence the percentage decrease is 2.9%
