Answer:
30 degress
Step-by-step explanation:
9(400 + 70 + 5). Distribute the nine to all the numbers in parentheses. 3600 + 630 + 45 = 4,275. 9 * 475 =4,275
Answer:
x = 6
Step-by-step explanation:
∡J = ∡K and ∡M = ∡L
because this is an isosceles trapezoid
∡J + ∡M = 180°
because angles at opposite bases are supplementary
then ∡J + ∡M = 180°
∡J = (7x + 2)°
∡M = ∡L = (25x - 14)°
so:
(7x + 2 + 25x - 14)° = 180°
(32x - 12)° = 180°
32x = 180 + 12
32x = 192
x = 6
X=amount of apples bought. (in pounds)
y=amount of bananas boutht (in pounds)
We can suggest this system of equations:
x+y=3.8
1.9x+0.75y=5.84
We can solve this system of euqtions by substitution method.
x+y=3.8 ⇒ y=3.8-x
1.9x+0.75(3.8-x)=5.84
1.9x+2.85-0.75x=5.85
1.15x=5.84-2.85
1.15x=2.99
x=2.99/1.15
x=2.6
y=3.8-x
y=3.8-2.6
y=1.2
Answer: C. 2.6 pounds of apples; 1.2 pounds of bananas.
