Answer:
1. Let's solve for x.
−3x+5y=−6
Step 1: Add -5y to both sides.
−3x + 5y + −5y = −6 + −5y
−3x = −5y − 6
Step 2: Divide both sides by -3.
−3x
−3
=
−5y−6

2. Let's solve for x.
6x−10y=12
Step 1: Add 10y to both sides.
6x−10y+10y=12+10y
6x=10y+12
Step 2: Divide both sides by 6.
6x

=
10y+12

The slope-intercept form of x - y = 7 is y = x - 7. The slope of that line is 1. That means the slope of the line that also goes through (1, 0) is also 1. If you use the point-slope formula, the answer you will receive is y = x - 1.
Answer:
<em>x = 110° ; y = 49°</em>
Step-by-step explanation:
m∠ABD = m∠ADB = 35° ⇒ <em>x</em> = 180° - 2 × 35° = <em>110°</em>
m∠CDB = m∠CBD = 2y ⇒ <em>y</em> = (180° - 82°) ÷ 2 = <em>49°</em>
Answer:
since there are 30 students as a whole and 20 boys make up part of the class, you can assume that there are 10 girls in the class. since the mean mark for boys is 62 I think the mean mark for girls would be 8%
Step-by-step explanation:
1 pound 2/3 + 1/3 = 3/3 simplify to get 1
