Answer:

x = 15/2

Step-by-step explanation:

Solve for x:

4 x + 12 = 42

Subtract 12 from both sides:

4 x + (12 - 12) = 42 - 12

12 - 12 = 0:

4 x = 42 - 12

42 - 12 = 30:

4 x = 30

Divide both sides of 4 x = 30 by 4:

(4 x)/4 = 30/4

4/4 = 1:

x = 30/4

The gcd of 30 and 4 is 2, so 30/4 = (2×15)/(2×2) = 2/2×15/2 = 15/2:

Answer: x = 15/2

Solve the formula t= 4u/e, for the variable e

Komok [63]

Answer:

$e=4u/t$

Step-by-step explanation:

we have

$t=\frac{4u}{e}$

Solve for the variable e

That means -----> Isolate the variable e

Multiply by e both sides

tex](e)t=\frac{4u}{e}(e)[/tex]

$et=4u$

Divide by t both sides

$e=4u/t$

Triangle E F G. Side E F is 6 meters, F G is 5 meters, E G is 7 meters. Angle F is 87 degrees and angle G is 58 degrees. Triangl

daser333 [38]

Answer:

Similar triangles

Step-by-step explanation:

Refer to attached

<u>Given:</u>

EF =6 m, FG = 5m, EG = 7 m
∠F = 87°, ∠G= 58°, ∠E = 180° -(87°+58°) = 35°

KL= 28 m, LJ = 24 m, JK = 20 m
∠J = 87°, ∠K = 58°, ∠L = 35°

∠F≅∠J, ∠G ≅ ∠K, ∠E ≅ ∠L

and

KL/EG = LJ/EF = JK/FG = 28/7= 24/6= 20/5 = 4

So the corresponding angles are congruent and corresponding sides are similar

We can conclude that the triangles are similar
