Answer:

Word problem: A recipe for making cookies use half cup of sugar for 1 cup of flour to make one pound of cookies. How many cups of sugar you need to make 3 pound of cookies.

As you can see to solve that problem you need to multiply the fraction 1/2, which is the number of cups needed to make 1 pound of cookies, times the number of pounds that you want to make.

So, for this problem you have to multiply 1/2 times 3.

My estimate is that the result is 1.5.

You can verify my estimate by multiplying:


        1        3x1       3
3 x ----- =  ------ = ------ = 1.5
        2.       1x2       2

So, I have shown that my estimate was correct.

never [62]

Answer:

C

Step-by-step explanation:

thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.

First, subtract 18 from both sides to eliminate it.

2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14

Next, separate the 2 from the x by dividing it from both sides:

2x = 14 ----> 2x/2 = 14/2 ----> x = 7

By solving this equation, we find that x, or one sandwich, costs $7.

In a G.P., the third term exceeds the first term by 16.
Tresset [83]

Answer:

Step-by-step explanation:

In a G.P, the nth term is given as

Un=ar^(n-1)

Where

a is first term

n is nth term

And r is common ratio

So in the question given above,

The third term exceed the first term by 16

i.e U3=U1+16

Where U1=a. First term

U3=a+16

Given also that, the sum if the third term and fourth term is 72.

Then U3+U4=72.

We are told to find common ratio (r)

U3=ar^3-1

U3=ar^2

Also, U4=ar^3

U3+U4=72

ar^2+ar^3=72

ar^2(1+r)=72. equation 1

Also for

U3=a+16

ar^2=a+16

ar^2-a=16

a(r^2-1)=16. From (x^2-y^2)=(x+y)(x-y)

Then,

a(r-1)(r+1)=16. Equation 2

Divide equation 2 by equation 1

a(r-1)(r+1)/ar^2(1+r) =16/72

Then a cancel a and (1+r) cancel (1+r)

So,

(r-1)/r^2=2/9

Cross multiply

9(r-1)=2r^2

2r^2-9r+9=0

Solving the quadratic equation

2r^2-6r-3r+9=0

2r(r-3)-3(r-3)=0

(r-3)(2r-3)=0

r-3=0. Or. 2r-3= 0

Then r=3 or r=3/2
