goblinko [34]
5(20) + 4y = 216
100 + 4y = 216
4y = 216 - 100
4y = 116
y = 116/4
y = 29.....so they sold 29 four-dollar yogurts + 20 five-dollar yogurts....for a total of 49 yogurts sold  <==

Question 7 of 33
astraxan [27]

Answer:

90°.

Step-by-step explanation:

When two straight lines intersects obliquely then there will be two angle of intersection, one angle is acute and the other one is obtuse.

But, here the two straight lines AB and xy intersects perpendicularly and AB bisects xy.

Therefore, the two angle of intersection are 90° each.

Hence, the angle of intersection in our case will be equal to 90°. (Answer)

If the line joining (3x, x+1) and (11,12) has a slope of 4 what is the value of x​
Irina18 [472]

Answer:

x = 3

Step-by-step explanation:

(3x,\: x +1)=(x_1, \:y_1)

(11,\: 12)=(x_2, \:y_2)

slope =  \frac{y_2 - y_1}{x_2 - x_1} \\  \\ 4 =  \frac{12 - (x + 1)}{11 - 3x}   \\  \\ 4 =  \frac{12 - x  -  1}{11 - 3x}   \\  \\ 4 =  \frac{11 - x}{11 - 3x}   \\  \\ 4(11 - 3x) = 11 - x \\  \\ 44 - 12x = 11 - x \\  \\ 44 - 11 = 12x - x \\  \\ 33 = 11x \\  \\ x =  \frac{33}{11}  \\  \\  \huge \red{ \boxed{x = 3}}

Round each mixed number to the nearest whole number. Then, estimate the quotient.
Anni [7]
You would round up because 24 16/17 is closer to 25 and 4 8/9 is closer to 5. 
which would be 25/5 which estimates to 5.
