Answer:

\textbf{HELLO!!}

0.7\left(1.5+y\right)=3.5y-1.47

1.05+0.7y=3.5y-1.47  \gets \textsl{Expand}

1.05+0.7y-1.05=3.5y-1.47-1.05  \gets Subtract\; 1.05 \from\:both\:sides

0.7y=3.5y-2.52

0.7y-3.5y=3.5y-2.52-3.5y

\mathrm{Subtract\:}3.5y\mathrm{\:from\:both\:sides} \nwarrow

-2.8y=-2.52

\frac{-2.8y}{-2.8}=\frac{-2.52}{-2.8} \hookleftarrow \mathrm{Divide\:both\:sides\:by\:}-2.8

\boxed{\boxed{\underline{\textsf{\textbf{y=0.9}}}}}

\bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet

\textbf{HOPE IT HELPS}

\textbf{HAVE A GREAT DAY!!}

Answer:

y = 0.9

Step-by-step explanation:

1.05 + 0.7y = 3.5y - 1.47

-3.5y + 0.7y = -1.47 - 1.05

-2.8y = -2.52

y = 9/10 = 0.9

Radio waves travel at the speed of light, 3.0 × 108 m/s. What is the wavelength of a radio wave from an AM station broadcasting
pochemuha

Answer:

4 × 10^2 M

Step-by-step explanation:

We are given;

Speed of light as 3.0 × 10^8 m/s

Frequency of radio wave as 7.5 × 10^5 Hz

We are required to determine the wavelength.

Using the formula;

wavelength, λ = v/f

Note; Radio wave is an electromagnetic wave, therefore travels with the speed of light.

Therefore;

wavelength, λ = 3.0 × 10^8 m/s ÷ 7.5 × 10^5 Hz

                      = 4 × 10^2 M

Hence, the wavelength of the radio wave is 4 × 10^2 M

The length of the base of an isosceles triangle is x. The length of a leg is 2x-6. The perimeter of the triangle is 23 . Find x.
expeople1 [14]

Answer:

In an isosceles triangle, the legs of the triangle have same lengths.

{ \tt{perimeter = side + side + side}}

• substitute:

{ \tt{23 = x + 2(2x - 6)}} \\  \\ { \tt{23 = x + 4x - 12}} \\  \\ {  \tt{5x = 35}} \\  \\ { \boxed{ \tt{ \:  \: x = 7 \:  \: }}}
