Answer:
x=924
Step-by-step explanation:
348 + 926 = x + 350
we have two 2-terms additions in both sides of the equation.
348 and 350 are two <em>similar</em> numbers then x and 926 should be really <em>close</em> numbers.
(due to commutative property of additions 348 + 926 = 350 + x)
<em>since 348 has two units less than 350, then 926 must have two units more than x, and <u>x=924</u></em>
(indirect proportionality)
Answer:
The value of x is 11
Step-by-step explanation:
<em>Two angles are complementary if the sum of their measures is 90°</em>
Let us use this rule to solve our question
∵ The angle of measure (3x)° and the angle of measure (5x + 2)°
are complementary angles
→ That means their sum equals 90°
∴ 3x + 5x + 2 = 90
→ Add the like terms in the left side
∵ (3x + 5x) + 2 = 90
∴ 8x + 2 = 90
→ Subtract 2 from both sides to move 2 from the left side to the right side
∵ 8x + 2 - 2 = 90 - 2
∴ 8x = 88
→ Divide both sides by 8 to find x
∵ 8x/8 = 88/8
∴ x = 11
∴ The value of x is 11
You should put 4 as x, -3 as y and a as slope to make an equation :
then you can find the slope and the correct equation of the line :
the slope is :
so the equation of the line will be
D is true
hope this helps
