Answers
Answer:
A) Lauren is 10 years old. 5*2=10
Twice means multiply by 2
B) Mark baked 6 muffins. 12* 1/2=6
Half as many means half of the number so half of 12 is 6.
C) Jerry made $24. 20+4=24
more means to add, so $4 more than Amy ($20) is 20+4.

How many solutions exist for the given equation?
1/2(x + 12) = 4x-1
zero
one
two
infinitely many
Answers
Answer:
one
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] (x + 12) = 4x - 1 ( multiply through by 2 to clear the fraction )
x + 12 = 8x - 2 ( subtract x from both sides )
12 = 7x - 2 ( add 2 to both sides )
14 = 7x ( divide both sides by 7 )
2 = x
There is one solution to the equation, that is x = 2

Answers
Answer:
x= 8 km
Step-by-step explanation:
measurement used:
When getting measurement the missing side occupies 1 more than a half of 15km
Answer:
x = 8km
Step-by-step explanation:
Use Pythagorean Theorem:
c2 = a2 + b2
In the diagram given, the hypotenuse (c) is 17 so substitute these values into the equation
17^2 = x^2 + 15^2
Take 15 to the power 2, to the other side.
17^2 - 15^2 = x^2
Solve to get
64 = x2
Square root both sides so
x = 8

Answer:
x=7/2y − 7
Step-by-step explanation:
Let's solve for x.
−2x+7y=14
Step 1: Add -7y to both sides.
−2x+7y+−7y=14+−7y
−2x=−7y+14
Step 2: Divide both sides by -2.
−2x/−2 = −7y+14/−2

Factor the trinomial 3x2 + 13x − 10 by grouping.
Answers
Answer:
(3x - 2) (x+5)
Step-by-step explanation:
3x^2 + 13 - 10
15× - 2 = -30
15+-2 = 13.....substitute 15x - 2x in place of 13x
3x^2+15x-2x-10
Factorise the first two values, thrn the second two
3x (x+5) - 2 (x+5)
Gathering the like terms together you eill be left with the following
(3x - 2) (x+5)
The factors of the trinomial 3x² + 13x - 10 is (3x-2)(x+5).
What is Factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.
we have,
Trinomial= 3x² + 13x - 10
Now, factories using splitting the middle term we get
3x² + 13x - 10
= 3x² + 15x - 2x - 10
= 3x( x +5) - 2(x+ 5)
= (3x - 2) (x+ 5)
So, the factors are (3x- 2(x+5)
