Answer:

145

Explanation:

The next number is 7 times the first, so 7x. Therefore the first number is 45, the second number is 7(45) or 315, and the third number is 100 + 45 to 145.

Answer:

Number 1: 49

Number 2: 343

Number 3: 149

Explanation:

Let x be the first number

The equation for this word problem would be: x+7x +100+x=541.

Solving for x:

x+ 7x +100+x=541.

9x+100=541

9x=441

x=49

Then, checking my answer:

49+7(49)+100+49=541

Do 7*49

49+343+100+49

Add all the numbers together

541=541

Then, using 49 as the first number, calculate the other numbers.

Number 1: 49

Number 2: 7*49 = 343

Number 3: 100+49 = 149

Hope this helps!

The answer is:

It will challenge Americans instead of protecting them.

The new deal is a set of government programs that is aimed to provided government funded help to address the great depression. But the unemployment still remain high years after the new deal and it increase united states debt, so it has to be ended.

The new frontier program was proposed to fund projects for space exploration. Kennedy believe that this is different from the new deal since it actually challenge American to learn and contribute rather than waiting around for government help
