A recipe for a cake calls for 3 cups of water. Elisa accidentally put in 6 cups. How many extra cups did she put in? What equation would depict this scenario?
c-3=6
c-6=3
c+3=6
c+6=3
Answer:
1.Elisa accidentally put in 3 extra cups of water
2.C+3=6
Solve the system below for x: (2 pts)
y = 6x + 4
y = 5x - 1
O X=-3
O X = -3/11
0 x = -5
x = -5/11
Answer:
x=-5
Step-by-step explanation:
6x+4=5x-1
x+4=-1
x=-5
Sam can type 20 words in 30 seconds how many words can he type in 90 seconds
Answer:

Step-by-step explanation:
90 divided by 30 is 3, so you would multiply 20 by 3 to get your answer of 60.
Hope this helps :)
Answer:
He can type about 51 words in 90 seconds because...
Use proportion!
7x = 360
X = 51 3/7
X is ABOUT 51

Answer:
2550.5
Step-by-step explanation:
We have a circle and are asked to find the area.
We know the diameter already, but the formula to find area requires a raidus, which is unknown to us yet.
To find radius, all you need to do is follow [tex]\frac{d}{2}[/tex]. D being diameter.
D = 57.
[tex]\frac{57}{2}= 28.5[/tex]
The radius is 28.5, now do the formula of area.
[tex]A = \pi *r^2[/tex]
[tex]A = \pi *28.5^2[/tex]
[tex]28.5^2[/tex]
[tex]812.25[/tex]
[tex]A=\pi *812.25[/tex]
[tex]A=3.14 * 812.25[/tex]
[tex]A = 2550.465[/tex]
Now we need to round to the nearest tenths, since 6 is the knowledge that we round up, round up.
[tex]2550.5[/tex]

Why is it important to understand how variables work, inequalities, and basic awareness of exponents before starting algebra?
Answer:
It is important because they are the basics of algebra. Almost every algebraic problem you will ever solve is based on these fundamental properties. In equations, we almost never know every part of it so we will need variables to substitute the unknown amount in an equation. Variables are used for basically every equation/problem in algebra. Inequalities are not as important as variables but are still really important. Inequalities are basically comparing numbers. And in algebra when they add variables into an inequality, the inequality will help lower the number of possible values of said variable. And exponents are just a basic operation in algebra. Just like learning addition and subtraction. It is like a quicker and less complicated way of multiplying numbers.
6 A rectangular room is 2 m longer than it is
wide. Its perimeter is 70 m. If the width of
the room is w m, express its length in terms
of zo. Hence find the width of the room.
Answer:
W = 16.5 meters
Step-by-step explanation:
let w be the width and then the length is w+2
Perimeter = 70 = 2w + 2(w+2)
70 = 2w + 2w + 4
4w = 66
w = 16.5 meters
y = 1/2x + 4
x - y = 8
*Substitution
Answer:
y=16, x=24
Step-by-step explanation:
First simplify: x-(1/2x+4)=8
Isolate x for 1/2x-4=8
Add 4 to both sides:
1/2-4+4=8+4
Simplify :1/2=12
Multiply both sides by 2:
2*1/2x=12*2
Simplify:
x=24
Substitute x=24:
y=1/2*24+4
1/2*24+4=16
1/2*24=12
12+4
Add the numbers: 12+4=16
y=16
The solutions to the systems of equations are:
y=16,x=24

Question # 1 : If Question # 2 : How are lines, rays, and segments different? How are they the same?
Answer:
A line segment has two endpoints. It contains these endpoints and all the points of the line between them. A segment is named by its two endpoints. A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray.

Write the equation for "25 more than a number x is the same as 44"
Answer:
25 + x = 44
Step-by-step explanation:
Substitute the words with the math symbols.
25 more than a number x is the same as 44
more than means to +
is the same as means =
25 more than a number x is the same as 44
25 + x = 44
25 + x = 44
why do systems of nonlinear equations sometimes have more than one solution
Answer:
System has equal number of unknowns and equations.
Manipulation easily yielded expressions for 4 of the 7 unknowns.
However it seems that the remaining 3 unknowns x,y,z are not fixed by the equations. Different combinations (x0,y0,z0) seem possible without violating the system equations.
Is this possible, or did I most probably make a mistake in counting degrees of freedom?
