Hello there, Today we will solve your math problem

{\huge{\boxed{\mathfrak{{Question}}}}

x+y=42\\x-6=5(-6)

________________

First off let's isolate x

after doing that we can substitute x for -12

Here is our equation

-12+y=4

solve for y and we get that y=16

________________

{\huge{\boxed{\mathfrak{{Answer}}}}

  1. {\boxed{x=-12}}
  2. {\boxed{y=16}}

Answer:

a) = 4.5

b) = 3.3

Step-by-step explanation:

Before solving our problems given to us let us under stand the rule of cube roots

It says \sqrt[3]{x \times x \times x} = x   -----(A)

Also

\sqrt[3]{x \times x \times x \times y \times y \times y} = x \times y   ---(B)

Now let us see each part one by one

a) we have

\sqrt[3]{64} + \sqrt[3]{0.027} + \sqrt[3]{0.008}

Now 64 = 4 x 4 x 4

0.027 = 0.3 x 0.3 x 0.3

0.008 = 0.2 x 0.2 x 0.2

substituting these values

\sqrt[3]{4 \times 4 \times 4} + \sqrt[3]{0.3 \times 0.3 \times 0.3} + \sqrt[3]{0.2 \times 0.2 \times 0.2}

Applying Rule A in above

=4+0.3+0.2

=4+0.5

4.5

b) we have \sqrt[3]{0.3 \times 0.3 \times 0.3 \times 11 \times 11 \times 11}

Applying the B rule in this

=0.3 \times 11

3.3

Melissa cut 2 and 1/4 feet of tape. How much is this in inches?
taurus [48]
1 ft = 12 inches

so 2 ft = (2 * 12) = 24 inches
and 1/4 ft = 1/4 * 12 = 12/4 = 3 inches

for a total of 27 inches

<u>Answer:</u>

  • The value of ∠TMV is 45°.

<u>Step-by-step explanation:</u>

<u>We know that:</u>

  • ∠VTM + ∠TMV + ∠MVT = 180°
  • ∠VTM = 92
  • ∠MVT = 43

<u>Work:</u>

  • ∠VTM + ∠TMV + ∠MVT = 180°
  • => 92 + 43 + ∠TMV = 180°
  • => 135 + ∠TMV = 180°
  • => ∠TMV = 180 - 135
  • => ∠TMV = 45°

Hence, <u>the value of ∠TMV is 45°.</u>

Hoped this helped.
