Five more than a number is equal to seven-halves of the number What is the number? HELP

Mathematics
1 answer:
natka813 [3]3 years ago

Answer:

The number is 2

Step-by-step explanation:

To attempt this question, we need to represent the number with (x).

Let the number be x

Five more than the number is:

5 + x

Seven-halves means 1/2 × 7 = 7/2

Mathematically, the question is saying:

5 + x = 7/2 × x

5 + x = 7x/2

Cross multiply;

2(5 + x) = 7x

10 + 2x = 7x

We collect like terms;

10 = 7x - 2x

10 = 5x

x = 10/5

x = 2

The number represented by x is 2

G varies inversely with the square
vivado [14]

Answer:;4.4

Step-by-step explanation: Since it varies inversely we know G times H squared is equal to some constant, k. So we have G*H*H=k. We are told that when H=4, G=.25. Plugging this in, we have .25*4*4=k. This simplifies to 4=k. Our new equation is G*H*H=4. Now, we want to solve for G when H=.3. We plug it in. G*.3*.3=4 => G*.09=4. G=4/.09. This means G is approximately 44.4.

In ΔKLM, k = 700 cm, l = 460 cm and ∠M=78°. Find the length of m, to the nearest centimeter.
pashok25 [27]

Answer:

753

Step-by-step explanation:

m^2 =700^2 +460^-2 −2(700)(460)cos78

m^2 = 490000+211600-2(700)(460)(0.207912)

m^2 = 490000+211600-133895.12889

m^2 = 567704.87111

m=753.462=753

Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. Using Monet's measurement, calculate th
Anon25 [30]

Answer:

5.495 inches.

Step-by-step explanation:

We have been given that Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. We are asked to find the circumference of an Oreo.

We know that circumference of circle is equal to 2\pi r, where r represents radius of circle.

We also know that diameter is 2 times radius.

D=2r

Upon substituting 2r=\text{ 1.75 in}, we will get:

\text{The circumference of an Oreo}=\text{ 1.75 in}\times \pi

Using 3.14 as an estimation for π, we will get:

\text{The circumference of an Oreo}=\text{ 1.75 in}\times 3.14

\text{The circumference of an Oreo}=5.495\text{ in}

Therefore, the circumference of an Oreo would be 5.495 inches.
