2. 45x
3. 16x+8y
4. y = -3x/5
Answer: $20.06
To find how much 18% of the cost is, convert the percentage to a decimal by dividing by 100. Then multiply that decimal to the cost.
18/100 = .18 (percentage as decimal)
17*.18 = $3.06 (18% of the cost)
3.06+17 = $20.06 (total price with tip of 18% and cost)
Answer:
615.75
Step-by-step explanation:
Answer:
m = -6
Step-by-step explanation:
Put this given equation into slope-intercept form:
y−15=−6(x+7) becomes y - 15 = -6x - 42.
Adding 15 to both sides results in y = -6x - 27,
and so the slope is -6. The y-intercept is -27, or (0, -27).
Answer:
<em>x = 17°, m∠ A = 114°</em>
Step-by-step explanation:
We can tell that these pair of angles are corresponding, provided;
Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,
m∠ A = m∠ B ⇒ Substitute values of A and B,
6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,
3x + 12 = 63 ⇒ Subtract 12 on either side of equation,
3x = 51 ⇒ Divide either side by 3,
<em>x = 17 </em>⇒ Substitute value of x to solve for m∠ A,
m∠ A = 6 * ( 17 ) + 12,
m∠ A = 102 + 12,
<em>m∠ A = 114</em>
<em>Solution; x = 17°, m∠ A = 114°</em>
