Answer:
The value of x is 5
Step-by-step explanation:
<em>The measure of the </em><em>exterior angle</em><em> at one vertex of a triangle equals the </em><em>sum of the measures of the two opposite interior angles</em><em> to this vertex</em>
In ΔQRS
∵ ∠QRS is an exterior angle of the triangle at vertex R
∵ ∠PQR and ∠RPQ are the opposite interior angles of vertex R
→ By using the rule above
∴ m∠QRS = m∠PQR + m∠RPQ
∵ m∠QRS = (10x - 10)°
∵ m∠PQR = (2x + 1)°
∵ m∠RPQ = (3x + 14)°
→ Substitute them in the equation above
∴ 10x - 10 = 2x + 1 + 3x + 14
→ Add the like terms in the right side
∵ 10x - 10 = (2x + 3x) + (1 + 14)
∴ 10x - 10 = 5x + 15
→ Subtract 5x from both sides
∵ 10x - 5x - 10 = 5x - 5x + 15
∴ 5x - 10 = 15
→ Add 10 to both sides
∵ 5x - 10 + 10 = 15 + 10
∴ 5x = 25
→ Divide both sides by 5 to find x
∴ x = 5
∴ The value of x is 5
Answer:
6
Step-by-step explanation:
The equation will be like this,
6.89 + t = 8.00
t = 8 - 6.89
t = 1.11
tips = $1.11
6.89 + t = 8.00
To sum up the total amount of cash and coins you have, first, sort each invoice and coin by denomination. Create a separate stack for each denomination and count how many denominations or coins you have.
For each denomination of banknotes and coins, multiply the number you have by the denomination. For example, if you have 4 out of $ 10, multiply by 4x10 to get $ 40. If you have three $ 5 bills, multiply by 3x5 to get $ 15.
Sum the totals to calculate the total amount.
