Solution:
Let's reread the part of the question carefully.
{one more} {than one third the number of dolls than Sally has}
↥ ↥
1 s/3
This means that Anne has s/3 + 1 dolls, which is 9 dolls.
=> s/3 + 1 = 9=> Sally/3 + 1 = AnneHence, the equation that represents the word problem is S/3 + 1 = A.
Find the value of x.
Answer:
x= 96
Step-by-step explanation:
an triangles angles always add up to 180 so 44+40 equals 84 and 180-84= 96.
If you're good at math, please help: Find the constants a and b such that the function is continuous on the entire real line.
Answers:
a = -2
b = -1
==========================================
Explanation:
The first piece 5 must match up with the ax+b when x = -2, or else the function wouldn't be continuous at this junction.
Plug in x = -2 and set the result equal to 5
We end up with -2a+b = 5
Solving for b gets us b = 5+2a
--------------
The middle piece ax+b must also equal the third piece -5 when x = 3 to ensure the second junction is continuous.
This leads us to the equation 3a+b = -5
Apply substitution and solve for 'a'
3a+b = -5
3a+5+2a = -5
5a+5 = -5
5a = -5-5
5a = -10
a = -10/5
a = -2 is one of the answers
Then use this to find b
b = 5+2a
b = 5+2(-2)
b = 5-4
b = -1 is the other answer

Answer:
W is 9
Step-by-step explanation:
18+4w=6w
-4w-4w
18=2w
/2 /2
w=9
Answer:
w = 9
Step-by-step explanation:
18+4w=6w
Rearrange terms
4w + 18 = 6w
Subtract 18 from both sides of the equation
4w+18-18=6w-18
Simplify
4w = 6w-18
Subtract 6w from both sides of the equation
4w-6w=6w-18-6w
Simplify
-2w=-18
Divide both sides of the equation by the same term
-2w/-2=-18/-2
w = 9

PLS HELP!!!! I don't understand how to answer this question!!!
Answer:
34
Step-by-step explanation:
Angle A and B are complementary which means they both add up to 90 degrees. Angle A is x+22 while angle B is only x. If we add both together, we can call angle A+B to be 2x+22. We can rewrite this as 2x+22=90. Take the 22 over to the other side and its sign changes so it is now 2x=90-22. 90-22=68 so now we have 2x=68. To isolate the x divide both sides by 2 which gives us x=34.

A 3m ladder stands on horizontal ground and reaches 2.8 m up a vertical wall. How far is the foot of the ladder from the base of the wall?
Step-by-step explanation:
let T be the top of the ladder
let F be the foot of the ladder
let B be the base of the wall
you need to find the distance between the foot of the ladder and the base of the wall, in other words the distance of the 'ground' ( refer to the diagram).
you are given that the hypotenuse - H is 3 m and that the opposite - O ( wall ) is 2.8 m.
i) find the angle
given
H, O → use SOH, sin.
sin x = opp. /hyp.
sin x = 2.8 / 3
x = sin-1 ( 2.8/ 3)
x = 68.960...
x = 70.0 ° ( 3 s.f)
ii) use either tan or cos to find the adjacent (wall)
using TOA, tan:
tan ( 68.96) = 2.8/ adj.
2.8 / adj. = tan (68.96)
adj. × tan (68.96) = 2.8
adj = 2.8/ tan (68.96)
adj = 1.0770...
adj. = 1.08 ( 3 sf)
base = 1.08 m
or you could rather simply work this out using Pythagoras Theorem:
where hyp. is c², the base is b² and height is a²;
c² = a² + b²
b² = c² - a²
b² = (3)² - (2.8)²
b² = 1.16
b = √1.16
b = 1.0770
b = 1. 08 m ( 3sf)
you can give your answer to 3 sf or 2 sf.
hope this helps you!

Juanita has $25, and she makes $11 per hour. She needs at least $58 to buy new shoes. Write and solve an inequality to determine how many hours Juanita must work to be able to buy new shoes. Then interpret the solution.
Answer:
Juanita must work 3 hours and above to be able to buy new shoes.
Step-by-step explanation:
Initially, Juanita has $25 and make $11 per hour
meaning, Juanita's new cash in hand after t hours is;
[tex]\tt C=25+11t[/tex]
Juanita needs at least $58 to buy new shoes;
meaning, the minimum cash Juanita should have should be $58 and above.
Simply put,
[tex]\tt C\geq 58[/tex]
[tex]---> \tt 25+11t\geq 58[/tex]
[tex]\tt --->11t\geq 58-25[/tex]
[tex]---> \tt 11t\geq 33[/tex]
[tex]----> \tt t\geq \frac{33}{11}[/tex]
[tex]---> \tt t>3[/tex]
The solution reveals that Juanita must work 3 hours and above to be able to buy new shoes.

h + 169 = 759 solve for h
Answer:
h = 590
Step-by-step explanation:
To find x, rearrange the equation to where h is on its own side.
Rearranged equation:
[tex]759 - 169 = h[/tex]
Since 169 added to h was to find 769, 169 subtracted from 759 represents h.
Solve:
[tex]759 - 169 = 590[/tex]
590 = h.

50 oz. of 12% sugar and 30 oz. of 20% sugar is needed to produce 80 oz. of 15% sugar.
EquationAn equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the amount of 12% sugar and y represent the amount of 20% sugar need to produce 80 oz. of 15% sugar. Hence:
x + y = 80 (1)
Also:
0.12x + 0.2y = 0.15(80) (2)
From both equations:
x = 50, y = 30
