x = -5

Step-by-step explanation:
Step 1: Define
4/(x + 1) = 3/(x + 2)
Step 2: Solve for x
Cross multiply: 4(x + 2) = 3(x + 1)Distribute: 4x + 8 = 3x + 3Subtract 3x on both sides: x + 8 = 3Subtract 8 on both sides: x = -5Answer:
to solve a proportion, you cross multiply. so you take the numerator of the first one, and multiply it by the denominator of the second one. and then the denominator of the first one is multiplied by the numerator of the second one:
4(x+2)=3(x+1) (set them = and then use the distributive property)
4x+8 = 3x+3 (subtract 3x from both sides)
x +8 = 3 (subtract 8 from both sides)
x= -5 (the answer)

Trigonometry Problem Solving
Two farmhouses A and B are 10.3km apart. A third farmhouse C is located such that angle A=83 degrees, and angle B=59 degrees. How far is C from A?
Step-by-step explanation:
Angle C = 180° - 83° - 59° = 38°
By Sine rule,
AC/sinB = AB/sinC
Therefore AC = ABsinB/sinC
= 10.3sin59°/sin38°
= 14.34km.

The order in which we complete an operation is NOT optional. This is because if we do addition or subtraction first, ( which is usually at the end of PEMDAS ) the answer ( even if it looks right ) will always be wrong. Always remember, if you don't do the regular PEMDAS, it will always be wrong.

Find the 10th term of the geometric sequence whose common ratio is 1/2
and whose first term is 5.
Answer:
[tex] {10}^{th} \: term = \frac{5}{512} [/tex]
Step-by-step explanation:
geometric progression formula:
[tex] {n}^{th} \: term = ar ^{n - 1} [/tex]
given:
common ratio, r = 1/2
[tex]first \: term \: = 5[/tex]
1) find the value of a
[tex] {n}^{th} \: term \: = a {r}^{n - 1} [/tex]
we're finding the 1st term, so substitute 1 into n:
[tex] {1}^{st} \: term = a( \frac{1}{2} ) {}^{1 - 1} [/tex]
first term is 5. so we substitute 5 into the equation:
[tex]5 = a(1)[/tex]
[tex]a = 5[/tex]
2) find the 10th term
we're finding the 10th term, so substitute 10 into the equation and don't forget to substitute 5 into a:
[tex] {10}^{th} \: term = 5( \frac{1}{2} ) {}^{10 - 1} [/tex]
[tex] {10}^{th} \: term = 5( \frac{1}{512} )[/tex]
[tex] {10}^{th} \: term = \frac{5}{512} [/tex]

x = 45
C
First 4 feet = 22
3 1/2 feet * 6 = 21
Total = 43

WILL MARK BRAINLIEST WHOEVER ANSWERS FIRST :DDDDDD
Answer:
528 cookies
Step-by-step explanation:
3 hours 55 minutes
=3×60+55
=235 and
235-215 ( for preheating minutes)
220
So
20 minutes…=48 cookies
1. ". =48/20 "
220 ". =48/20×220 "
=12/5×220 "
= 528 "
Answer:
well im not sure but i got 220
Step-by-step explanation:
so you convert the 3 hours and 55 minutes into minutes so
3*60=180
180+55=235
235-15=220
(for the preheating part)
220/48=4.583333333
4.583333333*48=(about)220 (actual number is 219.999999984)
so 220 cookies

At science camp, the kitchen served half of their blueberries with breakfast. After dinner, they put the remaining 5{,}270 \text{ g}5,270 g5, comma, 270, start text, space, g, end text of berries on top of their ice cream dessert. How many kilograms of blueberries did the science camp start with?
Answer:
10.54 kg
Step-by-step explanation:
Given that :
Half of blueberries is served with breakfast
The remaining 5270g is served with dinner
How many kilograms of blueberries did the science camp start with :
Total grams of blue berries :
(Grams served at breakfast + grams served at dinner)
Let total blueberries = x
x/2 + 5270 = x
(x + 10540) /2 = x
x + 10540 = 2x
10540 = 2x - x
x = 10540 grams
Amount of kilograms science camp started with = (10540) / 1000 = 10.54 kg

Solve for z. 2z − 3 = 1
Answer:
z = 2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
2z - 3 = 1
Step 2: Solve for z
Add 3 on both sides: 2z = 4Divide 2 on both sides: z = 2Which graph represents a system of equations with no solutions?
The last graph represents a system with no solutions. The solution to a system of equations is the point at which both lines intersect. Because the equations in the last graph don't intersect and are parallel, it has no solutions. Hope this helps :))

WILL GIVE BRAINLIEST AND 40 POINTS
Answer:
(3/10) * (x ^ 2)
Step-by-step explanation:
The first thing we are going to do is rewrite the expression correctly.
We have:
root (27x ^ 12 / 300x ^ 8)
Rewriting:
root ((27/300) * (x ^ 12 / x ^ 8))
root ((9/100) * (x ^ (12-8)))
root ((9/100) * (x ^ (4)))
root ((9/100) * (x ^ (4)))
3 * x ^ 2 * root ((1/100)
(3 * x ^ 2) / 10
(3/10) * (x ^ 2)
please Solve for x.
