Answer:

Step-by-step explanation:

m║n ⇒ (9x + 2)° = 74° {Corresponding Angles}

(9x)° = 72°

x = 8

Angles: angle corresponding to angle (5x-1)°, angle 74° and angle 2 add to 180° (straight angle)

(5×8 - 1)° + 74° + m∠2 = 180°

39° + 74° + m∠2 = 180°

113° + m∠2 = 180°

m∠2 = 180° - 113°

m∠2 = 67°

Jonah collects rainwater in a large barrel that weighs 30 pounds. When there are 10 gallons of water in the barrel, the total we

Serjik [45]

The first thing we are going to do for this case is define variables.
We have then:
x: number of gallons of water
y: total weight
We then have an equation of the form:
$y-yo = m (x - xo)
$
Where,
$m = (y2 - y1) / (x2 - x1)
$
Substituting values:
$m = (196.8 - 113.4) / (20 - 10)

m = 8.34$
We choose an ordered pair:
$(xo, yo) = (10, 113.4)
$
Substituting values:
$y-113.4 = 8.34 (x - 10)
$
Rewriting:
$y = 8.34x - 83.4 + 113.4

y = 8.34x + 30$
Answer:
y = 8.34x + 30

Without dividing, select the number that is divisible by 3.

Minchanka [31]

Answer: B. 1125
The answer is B because there is a special method when dividing by 3 to make sure it is actually able to be divided. You add the all the digits together, for example the digits in 1125, the total sum is 9 and if the total sum is able to be be divided by 3 then the whole number can be divided by 3.
