A factory has 203 workers. There are 70 more males than females. Let x represent the number of males and let y represent the number of females. Which system of equations represents this situation?
Equation:
X+Y=203
X=70
Answer:
x - y = 70 and x + y = 203 are the required system of equations represents this situation.
Step-by-step explanation:
Given that factory has 203 workers
Let "x" represent the number of males and let "y" represent the number of females
There are 70 more males than females. Which means,
Number of males = 70 + number of females
x = 70 + y
On rearranging we get,
x - y = 70 ----> equation 1
It is given that factory has 203 workers, which means number of males and females is equal to 203
Number of males + number of females = total workers
x + y = 70 ---- equation 2
So equation 1 and equation 2 represents the system of equations for this situation
x - y = 70 and x + y = 203 are the required system of equations

(Level 4) In a bag of orange, red, and yellow, 60% are orange, and 10% are red. There
are 6 yellow marbles in the bag. If you increase the number of orange marbles by 50%,
how many orange marbles are in the bag?
The answer is 22 orange marbles. Let me explain. Since 60% are orange and 10% are red, the rest, 30% is yellow. So we learn that every 10% equals to 2 marbles. If you add 60% + 50% = 110%
90% = 18
And we have to add 4 more because 10%×2.
So the total comes to 18+4= 22.

How many servings did the original recipe make?
Answer:
What equation will model the situation?
✔ x/3 = 4
How many servings did the original recipe make?
✔ 12
Step-by-step explanation:
Hope this helps!
The equation that represents the situation is x/3 = 4. And the number of servings that the original recipe makes will be 12.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Gary is making a dish yet they just necessities 1/3 of the first serving size. In the event that the quantity of servings Gary needs is 4.
Let 'x' be the number of servings. Then the equation is given as,
x/3 = 4
Simplify the equation, then we have
x / 3 = 4
x = 12
The condition that addresses what is happening is x/3 = 4. What's more, the number of servings that the first recipe causes will be 12.

Zoe needs to rent a car. Kara's Kar Kompany charges $22 per day and a $100 cleaning fee. Callie's Car Company charges $26 per day and has a $40 cleaning fee. After how many days would the rental cost be the same for both car rental companies
Answer:
15 days
Step-by-step explanation:
Step 1 - Put in equation form:
22d + 100 = t
26d + 40 = t
Step 2 - Simplify equations:
22d + 100 = 26d + 40
100 - 40 = 26d - 22d
60 = 4d
d = 60/4
d = 15

Find the perimeter of this semi-circle with diameter, d = 65cm. Give your answer rounded to 1 DP.
Answer:
1658.3
Step-by-step explanation:
the perimeter of a semi - circle is simply half the circumference of a circle.
that is ;
1 / 2 ( pi ( r² ) )
where;
pi = 3.14 ( this is a constant that should be known and also equals 22 / 7 )
r = radius ( or half a diameter )
in our question, we are given a diameter with no radius
this means that we will have to halve the diameter to give us our radius
that is;
d = 65cm
r = 65 / 2
r = 32.5
so, using our formula;
1 / 2 ( 3.14 ( 32.5² ) )
1 / 2 ( 3.14 ( 1056.26 ) )
1 / 2 ( 3316.65 )
1658.3125
rounded to 1 DP;

Answer:
x = -8
Step-by-step explanation:
1. Because the line the angles x + 96 and 100 + x are on is straight, it's a straight angle that results in 180°.
2. Given the above information, that means x + 96 + 100 + x = 180.
3. (Solving for equation above)
Step 1: Simplify both sides of the equation.
[tex](x+x) + (96+100)=180[/tex] [tex]2x + 196 = 180[/tex]Step 2: Subtract 196 from both sides.
[tex]2x + 196 - 196 = 180 - 196[/tex] [tex]2x = -16[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{-16}{2}[/tex] [tex]x = -8[/tex]Step 4: Check if solution is correct.
[tex]-8 + 96 + 100 - 8 = 180[/tex] [tex]88 + 100 - 8 = 180[/tex] [tex]188-8=180[/tex] [tex]180=180[/tex]Therefore, x = -8.
Answer:
x = - 8
Step-by-step explanation:
x + 96 and 100 + x are adjacent angles on a straight line and sum to 180°, so
x + 96 + 100 + x = 180 , that is
2x + 196 = 180 ( subtract 196 from both sides )
2x = - 16 ( divide both sides by 2 )
x = - 8

how do i work out -2=6+a/5
Answer:
a = -40
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]-2 = 6 + \frac{a}{5}[/tex] [tex]-2 = 6 + \frac{1}{5}a[/tex] [tex]-2 = \frac{1}{5}a + 6[/tex] [tex]\frac{1}{5}a + 6 = -2[/tex]Step 2: Subtract 6 from both sides.
[tex]\frac{1}{5}a + 6 - 6 = -2 -6[/tex] [tex]\frac{1}{5}a = -8[/tex]Step 3: Multiply both sides by 5.
[tex]\frac{1}{5}a * 5 = -8 * 5[/tex] [tex]a = -40[/tex]Therefore, a = -40. I hope this helped you!
Answer:
-40 = a
Step-by-step explanation:
-2=6+a/5
Subtract 6 from both sides of the equation-8 = a/5
Multiply both sides by 5(5)-8 = a/5(5)
-40 = a

An equilateral triangle has sides of length 16.1 cm, correct to the nearest millimetre.
Find the lower and upper bounds of the perimeter of the triangle.
Answer:
48.3 cm is the lower and upper bound of the perimeter.
Step-by-step explanation:
For any equilateral triangle, by definition, the
lengths of the sides of the triangle are the same.
Thus, the perimeter of the triangle is 16.1 + 16.1 + 16.1 = 3(16.1) = 48.3 cm.
Thus, the upper and lower bounds are the same and are both equal to
48.3 cm.
