Answer:
70[tex]x^{2}[/tex]+30x-140
Step-by-step explanation:
(7x+3) (10x-14)
70[tex]x^{2}[/tex]-98+30x-42
70[tex]x^{2}[/tex]+30x-42-98
70[tex]x^{2}[/tex]+30x-140
Answer:
x = 9
Step-by-step explanation:
These are vertical angles, and thus the angles are equal.
7x + 3 = 10x - 24
Combining like terms, we get
27 = 3x, so that x must be 9.
x = 9

Please help, I'm having a hard time with this ;-;
Answer:
A
Step-by-step explanation:
3 times steep means slope is 3 times
slope=4
new slope =3×4=12
translated 7 down means y intercept-7=1-7=-6
so new eq. is y=12x-6
Answer:
A
Step-by-step explanation:
So we know that the slope is 4, and we want to make it 3 times as steep, so that would be 12. The y-intercept is one and we want to move it down 7 units, 6-7= -1. So our final answer would be y= 12x-6!

I would go with option 4
Step-by-step explanation:
Answer:
[tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}[/tex]
[tex]\frac{x}{sin25} = \frac{32}{sin90}[/tex]
[tex]x = \frac{32sin25}{sin90}[/tex]

Evaluate the algebraic expression 4v-3 if v= -5.explain
Answer:
-23
Step-by-step explanation:
Given 4v-3
evaluate when v = -5
So basically we want to find the value of the expression when the variable (v) equals -5
so
* plug in -5 for v*
4(-5)-3
4*-5=-20
-20-3=-23
So we can conclude that when v = -5 the value of the expression is -23
Answer:
4v-3 = -23Explanation:
given the expression: 4v-3
if v = -5
4v-3 (let's subsitute v)
4v-3 = 4×(-5)-3
4v-3 = -20 - 3
4v-3 = -23

The diameter of a circle is 11 cm. Find its area to the nearest tenth.
Answer:
95.0
Step-by-step explanation:
Area of a circle
A = πr2
Radius is half the diameter = 11/2 = 5.5
A = π x 5.5 x 2
= 95.033177...
= 95.0

Step-by-step explanation:
The given recipe makes 8 bags.
To make 16 bags, Lily needs twice as many ingredients because 8 + 8 = 16.
Since 1 cup of raisins makes 8 bags, 2 cups of raisins will make 16 bags.
To show the mathematical way:
Variable w = number of cups of raisins
1/8 = w/16
Cross multiply
1 × 16 = 8 × w
16 = 8w
2 = w
2 cups of pretzels makes 8 bags so 6 cups of preztels will make how many bags?
Set up an equation:
Variable x = number of bags
2/8 = 6/x
Cross multiply
2 × x = 8 × 6
2x = 48
x = 24
6 cups of pretzels will make 24 bags.
If 0.5 cup of pecans = 2.5 cups of crackers, then 1 cup of pecans = y cups of crackers?
Variable y = number of cups of crackers
Set up equation:
0.5/2.5 = 1/y
Cross multiply
0.5 × y = 2.5 × 1
0.5y = 2.5
y = 5
1 cup of pecans will need 5 cups of crackers
2 cups of pretzels = 8 bags, so 1 cup of preztels = z bags?
Variable z = number of bags
Set up equation:
2/8 = 1/z
Cross multiply
2 × z = 8 × 1
2z = 8
z = 4
A teacher wants to choose a student at random. The teacher decides to choose the first person to walk through the classroom door at the start of the lesson.
a. Explain why this is not a good method.
2. Suggest a better method.
Answer:
The first person to arrive is not random. The person that mostly arrives first every time is the person who lives closest to the school, or is a teacher's pet.
The odds of the person who lives 20km away from the school being first are way lower than anyone else.
A better method, would be everyone writes their name on a paper, and the teacher picks one at random from a hat.

the local market is selling a pound of bananas for $0.55. if you bought 8 bananas for $1.44, what is the unit rate?
Answer:
$0.18
Step-by-step explanation:
Given that :
Number of bananas purchased = 8
Cost at which the 8 bananas were purchased = $1.44
The unit price of bananas can be obtained using the relation :
Total Cost of bananas / number of bananas
Unit price = $1.44 / 8
Unit price = $0.18
Price per unit of banana = $0.18

Pl help it’s for a grade
Step-by-step explanation:
Given,
1. The given expression is [tex]\sqrt[10]{x^9}[/tex].
We need to write it into exponential form.
We know that,
[tex]\sqrt[a]{x} =x^{1/a}[/tex]
Here, a = 10
So,
[tex]\sqrt[10]{x^9}=(x^9)^{1/10}\\\\=x^{9\times \dfrac{1}{10}}\\\\=x^{9/10}\\\\=x^{0.1}[/tex]
2.
[tex](\sqrt[4]{3y} )^3\\\\=((3y)^3)^{1/4}\\\\=3^{3\times \dfrac{1}{4}}\times y^{3\times \dfrac{1}{4}}\\\\=3^{3/4}y^{3/4}[/tex]
Hence, this is the required solution.
