Deondra has $12 to spend on a mixture of green and red grapes. What equation can she use to graph a line showing the different amounts of green and red grapes she can buy for $12?
No equation really.
I guess she could just by 2 lb green grapes and 3 lb red grapes.
Maybe because I didn't understand the question completely.
Evaluate [tex]\frac{bd}{a}[/tex] + c if a=−2a=-2 , b=3b=3 , c=−12c=-12 , and d=−4
Answer:
{a,c,d,b} = {49/16,29/16,2,-31/48}
Step-by-step explanation:
[1] 3a + c - 4d = 3
[2] -4a + 4c + d = -3
[3] -a - 2d + 3b = -9
[4] - d = -2
// Solve equation [4] for the variable d
[4] d = 2
// Plug this in for variable d in equation [1]
[1] 3a + c - 4•(2) = 3
[1] 3a + c = 11
// Plug this in for variable d in equation [2]
[2] -4a + 4c + (2) = -3
[2] -4a + 4c = -5
// Plug this in for variable d in equation [3]
[3] -a - 2•(2) + 3b = -9
[3] -a + 3b = -5
// Solve equation [1] for the variable c
[1] c = -3a + 11
// Plug this in for variable c in equation [2]
[2] -4a + 4•(-3a+11) = -5
[2] -16a = -49
// Solve equation [2] for the variable a
[2] 16a = 49
[2] a = 49/16
// Plug this in for variable a in equation [3]
[3] -(49/16) + 3b = -5
[3] 3b = -31/16
[3] 48b = -31
// Solve equation [3] for the variable b
[3] 48b = - 31
[3] b = - 31/48
// By now we know this much :
a = 49/16
c = -3a+11
d = 2
b = -31/48
// Use the a value to solve for c
c = -3(49/16)+11 = 29/16
Step-by-step explanation:
so bd/a+c= 3×(-4)/-2 +(-12)= -12/-2+(-12)=6+(-12)=6-12=-6
so the answer is -6

A pancake recipe calls for 4 cups of flour and 3 cups of milk. Does a recipe calling for 2 cups of flour and 1.5 cups of milk use the same ratio of flour to milk?
Answer:
I think the answer is Yes
Step-by-step explanation:
For example, 2 cups of flour can equal 4 cups of flour by multiplying by two. So 1.5 cups of milk, you multiply by two and it is equivalent to 3 cups of milk. So in the end, it is equal and it's basically half of the pancake recipe. Hope it helps!

Use the formula for the perimeter of a rectangle, P = 2 l + 2 w, where P is the perimeter, l is the length, and w is the width.
Answer:
The perimeter of the tabletop is 152 inches
Step-by-step explanation:
So if P = 2L + 2W we have to do
(2*48) + (2*28)
So
96 + 56 = 152

There are 11 counters in a bag.
8 of the counters are green.
3 of the counters are blue.
Sid takes at random two counters from the bag.
Work out the probability that Sid takes one counter of each colour.
Answer:
For a green and a blue P1 = 8/11 * 3/10 = (80 * 33) / 110^2 = .218
For a blue and a green P2 = 3/11 * 8/10 = (30 * 88) / 110^2 = .218
The probabilities are the same
The probability that Sid takes one counter of each color green and blue from the 11 counters in a bag is 48/121.
What is an additional rule of probability?When two events P(A) and P(B) occurs one time in an event of which occurs two times. Then the probability of occurring exactly one time both events is,
[tex]P=P(A)\times P(B)+P(B)\times P(A)[/tex]
There are 11 counters in a bag. In which,
8 of the counters are green.3 of the counters are blue.Sid takes at random two counters from the bag. Probability that Sid takes green counter is,
[tex]P(A)=\dfrac{8}{11}[/tex]
The probability that Sid takes blue counter is,
[tex]P(A)=\dfrac{3}{11}[/tex]
The probability that Sid takes one counter of each color is,
[tex]P=\dfrac{8}{11}\times\dfrac{3}{11}+\dfrac{3}{11}\times\dfrac{8}{11}\\P=\dfrac{24}{121}+\dfrac{24}{121}\\P=\dfrac{48}{121}[/tex]
Thus, the probability that Sid takes one counter of each color green and blue from the 11 counters in a bag is 48/121.

What numbers can be used instead to x for this equation to remain the same -x>2
Answer:
2x + 1 = 11.
2x + 1 - 1 = 11 - 1 (subtracting both sides by the same number)
2x = 10.
2x/2 = 10/2 (dividing both sides of the equation by the same number)
x = 5.
