Answer:

x = 7

y = 3/2 or 1.5 (IF THE ANGLE IS 30 BY THE RATIOS OF A RIGHT TRIANGLE.)

hope it's right

Step-by-step explanation:

FOR X:

Let's solve your equation step-by-step.

4x+3=31

Step 1: Subtract 3 from both sides.

4x+3−3=31−3

4x=28

Step 2: Divide both sides by 4.

4x/4=28/4

x=7

FOR Y:

Step 1: Simplify both sides of the equation.

(3)(7)+6y=30

21+6y=30

6y+21=30

Step 2: Subtract 21 from both sides.

6y+21−21=30−21

6y=9

Step 3: Divide both sides by 6.

6y/6=9/6

y=3/2

In the following figure find a deg,2adeg and bdeg
vampirchik [111]
From the figure. a and b are equal because the lines are parallel. The jargon is alternate interior angles are equal.

The two remote interior angles are equal to the exterior angle. That interprets to
b + 2a = 84o But b = a
a + 2a = 84o
3a = 84
a = 84/3
a = 28 <<<< answer
b = 28 <<<< answer
2a = 56 <<<< answer.

Someone help me with this ples with steps
SSSSS [86.1K]

Answer:

x=\frac{21}{4}

y=\frac{21}{2}

Step-by-step explanation:

equation (1): \frac{1}{2} (2x+y)=\frac{21}{2}

equation (2): y=2x

solve the system by substitution

step1: sub (2x) for y in equation 1:

\frac{1}{2} (2x+y)=\frac{21}{2}

\frac{1}{2} (2x+2x)=\frac{21}{2}

step2: simplify the expression:

\frac{1}{2} (4x)=\frac{21}{2}

2x=\frac{21}{2}

(divide by 2 for both sides)

x=\frac{21}{4}

To find the value for y sub 21/4 for x in equation 2:

y=2x

y=2×(21/4)

y=\frac{21}{2}
