Answer:

Step-by-step explanation:

What is the X

3x +15 and 2x + 20

assuming that the question is an equation

3x + 15 = 2x + 20

3x - 2x = 20 - 15

x = 5

-----------------

check

3 * 5 + 15 = 2 * 5 + 20

30 = 30

the answer is good

Answer:

$\sf y=\dfrac{5}{3}x+4$

Step-by-step explanation:

<u>Given:</u>

<u /> $\textsf{slope of $\dfrac{5}{3}$, and a y-intercept of $4$}$

⇒ Slope-Intercept Form: y = mx + b

<u>where:</u>

m is the slope
b is the y-intercept (when x = 0)

Substitute the given values:

$\sf\\ \implies y=mx+b\\\\\implies y=\dfrac{5}{3}x+4$

Given: Triangles ABC and DBC are isosceles, m∠BDC = 30°, and m∠ABD = 155°. Find m∠ABC, m∠BAC, and m∠DBC.

just olya [345]

∠BDC=30, so ∠CBD + ∠BCD=180-30=150
ΔDBC is isosceles, so ∠CBD=∠BCD=half of 150=75
∠ABC=∠ABD-∠CBD=155-75=80
ΔABC is isosceles, so ∠ABC=∠ACB=80
∠BAC=180-80-80=20
