Step-by-step explanation:
If the lake's level rose 4 inches and in June it rose 2 more inches, the total amount of distance that he rose is (4+2).
Also if the lake's level fell 5 inches in July and 3 more inches in August as a result of no rain, then the total amount of fall will be (5+3).
Change in height of the lake = total rise in distance - Total fall in distance
Change in height of the lake = (4+2) - (5+3) = (5+3) - (4+2) {commutative law}
open the parenthesis
(4+2) - (5+3)= 4+2-5-3 (note that minus times plus will give minus)
Hence the expressions that best describe this situation are;
1. (4+2) - (5+3)
2. (5+3)-(4+2)
3. (4+2) - 5 -3
At a candy store, Jeremiah bought 1 pound of jelly beans for $9. Meanwhile, Emma bought 4
pounds of jelly beans and 6 pounds of gummy worms for $60. How much does the candy
cost?
Plz help ASAP
Answer:
I think the candy cost 51 dollars
Jellybeans: 36$
Gummy worms: 15$
36 + 15 = 51
Step-by-step explanation:
Since jeremiah bought 1 pound for 9 dollar you can minus 9 from the equation which is 51 and since each pound of jelly beans were 9 dollars 9 x 4 = 36 and 51 - 36 is 15 so the cost of the gummy worms are 15 so
either 51 or 36 and 15

Remember that all angles add up to 180, and because you know that one of the angles = 90, you can add the other two angles like so.
6x + 15 + 10x - 5 = 90

Angle 1 = 43 degrees
Angle 3 = 32 degrees

If there are 62 boys out of 100 grade 7 students, how do you know this is in fractional form? What is the decimal form?
I know this is in fraction form because it says out of. A fraction will say out of, for example: 3 out of 4. The number 62 boys out of 100 students can be represented as 0.62, 0.62 of 1 (100) whole number.

Write the equation for a parabola whose vertex is (-6,-1) and passes through (-12,17).
Answer:
[tex]y=\frac{1}{2}(x+6)^2-1[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that graphically represents the function, and a is a coefficient different from zero.
The vertex of the required equation is located at (-6,-1)
The parabola passes through (-12,17)
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x+6)^2-1[/tex]
The value of a will be determined by using the given point:
[tex]17=a(-12+6)^2-1[/tex]
Operating:
[tex]17=a(36)-1[/tex]
[tex]36a=18\Rightarrow a=18/36=1/2[/tex]
Solving:
[tex]a=1/2[/tex]
The equation of the parabola is:
[tex]\boxed{y=\frac{1}{2}(x+6)^2-1}[/tex]
Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or saying “ degrees” after the number
Answer:
z = 29°
Step-by-step explanation:
We know that the 3 angles in a triangle always add up to 180°. So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).
angle A + angle B + angle C = 180°
59° + 92° + z = 180°
151° + z = 180°
Subtract 151° from both sides of the equation
z = 180° -151°
z = 29°

Sydney applied the steps below to find the product of (3.1)(–1.6). Step 1: (3.1)(–1.6) = (–1.6)(3.1) Step 2: = _______________ Step 3: = (–4.8) + (–0.16) Step 4: = –4.96 Which expression correctly fills in the blank in Step 2?
Answer:
(-1.6)(3 + 0.1)
Step-by-step explanation:
Sidney applied the steps to find the product of two numbers (3.1) and (-1.6),
Step 1,
(3.1)(-1.6) = (-1.6)(3.1)
Step 2,
(-1.6)(3.1) = (-1.6)(3 + 0.1)
Step 3,
(-1.6)(3 + 0.1) = -4.8 + (-0.16) [Distributive property]
Step 4,
-4.8 + (-0.16) = -4.96
Therefore, expression that correctly fits in step 2 will be,
(-1.6)(3 + 0.1)

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things. In daily speech, a line segment with two points designating its endpoints is also referred to as a line.
The line is shown below.

Given f(x) = 70 + 11x, find x when f(x) =158
Answer:
[tex] \huge \boxed{x = 8}[/tex]
Step-by-step explanation:
f(x) = 70 + 11x
To find the value of x when f(x) =158 , equate f(x) to 158
We have
[tex]70 + 11x = 158 \\ 11x = 158 - 70 \\ 11x = 88[/tex]
Divide both sides by 11
[tex] \frac{11x}{11} = \frac{88}{11} \\ [/tex]
We have the final answer as
x = 8Hope this helps you
