Answer:

$\Huge\boxed{x=12}$

Step-by-step explanation:

Hello There!

The following angles are complementary angles

Complementary angles have a sum of 90

So to solve for the variable (x) we use this equation

90 = 35 + 4x + 7

step 1 combine like terms

35+7=42

now we have

90 = 4x + 42

step 2 subtract 42 from each side

90 - 42 = 48

42 - 42 cancels out

now we have

48 = 4x

step 3 divide each side by 4

4x/4 = x

48 / 4 = 12

we're left with x=12

stich3 [128]

Answer: 254 ft

Step-by-step explanation:

Hi, to answer this we have to apply the formula for the area of a circle when we know the diameter.

Area of a circle (A)= (π/4) x D^2

Where D is the diameter

Replacing with the values given:

A = (π/4) x 18^2 = (3.14/4) x 324 =254.34 feet.

The sum of 3 numbers is 145. Seven times the second number is twice the first number and twice the second number is six times th

igor_vitrenko [27]

Answer:

$\frac{7}6}$

Step-by-step explanation:

Let the 3 numbers be $x,y,$ and $z$

As per question,

$x+y+z=145$

Also, 7 times the second number is twice the first, so

$7y=2x\\\frac{x}{y}=\frac{7}{2}----------- 1$

Again, twice the second number is 6 times the third number, so

$2y=6z\\\frac{2}{6}=\frac{z}{y}\\\frac{z}{y}=\frac{1}{3}---------- 2$

Now, multiply equations 1 and 2. This gives,

$\frac{x}{y}\times \frac{z}{y}=\frac{7}{2}\times \frac{1}{3}\\\frac{x\times z}{y\times y}=\frac{7\times 1}{2\times 3}\\\frac{xz}{y^2}=\frac{7}{6}$

Therefore, the ratio of the product of the first and the third numbers to the square of the second number is $\frac{7}6}$
