Answer:
d = -13
Step-by-step explanation:
-8.3 = d + 4.7
-8.3 - 4.7 = d
-13 = d
-8.3=d+4.7
What you want to do is flip the equation like this:
d+4.7=-8.3
The next step is to subtract 4.7 from both sides of the equation:
d+4.7=-8.3
-4.7 (both sides)
this equals to d=-13
Your final answer is d=-13 (negative 13).

What two numbers multiplied equal 6 but added together equal -7?
Answer:
-6 and -1
Step-by-step explanation:
let's suppose there are two numbers x and y so that it that works that would give the following equations
[tex]x*y=6 \\ x+y =-7[/tex]
now let'S rewrite the first to the form y =
[tex]y=\frac{6}{x}[/tex]
and plug that into the second one
[tex]x+\frac{x}{6} = -7|*6\\6x+x=-42\\7x=-42|:7\\x=-6[/tex]
use that to find out what y is
[tex]-6+y=-7|+6\\y=-1[/tex]
you can check that with the first equation

What is the solution to the system of equations below?
y=-1/3x+6
and x = -6
(-6,8)
(-6,4)
(8,-6)
(4, -6)
Answer:
(-6,8) is the answer using substitution method.
Step-by-step explanation:
y= (-1/3)(-6)+6
y= 2+6
y=8, x=-6
=(-6,8)
Answer:
The solution to this system of equations is [tex](x,y) = (-6, 8)[/tex].
Step-by-step explanation:
Since the number of equations and number of variables is the same, there is only one solution. Let [tex]y = -\frac{1}{3}\cdot x + 6[/tex] and [tex]x = -6[/tex], the solution of this system is found by evaluating the first function, that is:
[tex]y = -\frac{1}{3}\cdot (-6)+6[/tex]
[tex]y = 2+6[/tex]
[tex]y = 8[/tex]
The solution to this system of equations is [tex](x,y) = (-6, 8)[/tex].

My 11 year old sister needs help.
Answer:
1¼ pounds
or 1.25 pounds
Step-by-step explanation:
The lightest bunch = ⅛*5 = ⅝
The heaviest bunch = 1(⅛*+7) = 1⁷/8
Find the difference between the heaviest and the lightest bunch
1⅞ - ⅝
= 15/8 - 5/8
= (15 - 5)/8
= 10/8
= 5/4
= 1¼ pounds
or 1.25 pounds
The diagram shows a plastic solid made by joining a hemisphere to a cone. The radius of the hemisphere is 5cm and the height of the cone is 12cm.
i) Calculate the volume of the solid.
ii) Calculate the total surface area of the solid.
Answer:
575.8 cubic cm
Step-by-step explanation:
V(cone) = 1/3· π · r² · h
V = 1/3 · π · 25 · 12
V = 4(25)π or 100π = 314
V(half-sphere) = (4/3 · π r³)/2
V = (4/3π · 125) = 261.8

A recipe for one batch of cookies uses 5 cups of flour and 2 teaspoons of vanilla.
Complete the double number line diagram to show the amount of flour and vanilla needed for 1, 2, 3, 4, and 5 batches of cookies.
If you use 20 cups of flour, how many teaspoons of vanilla should you use?
If you use 6 teaspoons of vanilla, how many cups of flour should you use?
Explain how you would determine how much flour and vanilla would be needed for 9 batches of this cookie recipe.
Answer:
8 teaspoons of vanilla
15 cups of flour
Step-by-step explanation:
Since 20 is 4 x 5
And the flour and vanilla has to be proportionate, You also have to multiply 2 tablespoons of vanilla by 4
4 x 2 = 8

(a) An angle measures 61°. What is the measure of its supplement?
(b) An angle measures 39'. What is the measure of its complement?
Answer:

A study is done by a community group in two neighboring colleges to determine which college graduates students with more math classes. College A samples 11 graduates. Their average is 4 math classes with a standard deviation of 1.5 math classes. College B samples 9 graduates. Their average is 3.5 math classes with a standard deviation of 1 math class. The community group believes that a student who graduates from college A has taken more math classes, on the average. Test at a 1% significance level.

b=124p
just plug then in and solve
Answer:
20 plantains and 2480 bananas
Step-by-step explanation (b is bananas + p is plantains):
2500 = b+p
b=124*p
2500=(124*p)+p
2500=125p (divide by 125)
20=p
