One
Step-by-step explanation:
There will be one unique solution of the equation y = 5x - 1 and y = 3x + 7. The correct option is B.
What is a system of equations?A finite collection of equations for which we searched for common solutions is referred to in mathematics as a system of equations, sometimes known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized.
A linear equation can only have one unique solution, which is a location at which the LHS and RHS of the equation are equal. There is only ever one solution to a linear equation with one variable.
y = 5x - 1
y = 3x + 7
5x - 1 = 3x + 7
2x = 8
x = 4
y = 19
Therefore, there will be one unique solution of the equation y = 5x - 1 and y = 3x + 7.

bob is twice as old as ralph. three years ago the sum of their ages was 45. what are their ages now?
answer using a let statement
Answer:
Were they both 45? I'm kinda confused on that part, but I think Ralph would be 48 and Bob would be 50
Step-by-step explanation:
Answer:
34 and 17
Step-by-step explanation:
Bob = B
Ralph = R
B=2R
B-3+R-3=45
B+R-6=45
+6 +6
B+R=51
Substitute B for 2R
2R+R=51
3R=51
R=17
2(17)=34
so B is 34 and R is 17

The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.
What is Area ?Area is the space occupied by a two dimensional object,
The area and perimeter of the given shape can be determined by dividing it into basic shapes.
here, we have,
The area and the perimeter of the shape given
= Area of the rectangle +Area of upper triangle - Area of two small triangles at the bottom
Area of rectangle = 5 mi * 9 mi = 45 sq.mi
Area of upper Triangle = (1/2) *9*3 = 27/2 sq.mi
Area of small Triangle = (1/2) * 3*6 = 9 sq.mi
Area of other small Triangle = (1/2)*3*3 = 9/2 sq.mi
Area of the figure = 45 +13.5 -9-4.5
Area of the figure = 45 sq.mi
Similarly for Perimeter = Perimeter of the rectangle +Perimeter of upper triangle -Perimeter of two small triangles at the bottom
Perimeter = 28 -(3+6+6.708) -(3+3+4.2426) +(3+9+9.486
Perimeter = 23.5354 mi
Therefore , The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

what is the slope of the line with the following equation? (y-3)= -4(x-5)
Answer:
slope = - 4
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 4(x - 5) ← is in point- slope form
with slope m = - 4
Answer:
-4
Step-by-step explanation:
First express it in the form of y=mx+b where m is the slope and b is the y-intercept
y-3=-4x+20
y=-4x+20+3
y=-4x+23 then m=-4 which is the slope
Solve the equation for y. y-x=5
y - x = 5
y = x + 5

Step-by-step explanation:
A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the middle of the garden measures 30 feet. What is the distance around the perimeter of the garden? 120ft.
The perimeter of the rhombus is P = 120 feet
What is the perimeter of Rhombus?A Rhombus has four sides of the same length, its perimeter can be determined using the formula Perimeter = 4a, where "a" stands for the side's length.
When the two diagonals of a rhombus are known,
The perimeter = 2√p² + q²
where 'p' and 'q' are the diagonals.
Given data ,
Let the rhombus be represented as ABCD
Let the side length of the rhombus be AB = 30 feet
And , perimeter = 2√p² + q²
And , P = AB + BC + CD + AD
Due to the four triangles' similarity, we may conclude that AC is divided at O. So, we are aware that AO = 15 feet.
In ΔAOD,
(Perpendicular/hypotenuse) = sin 30°
or, 1/2 = 15/AD
otherwise, AD = 15 x 2 = 30 ft
So, AD equals 30 feet.
Given that all of a rhombus' sides are equal and all four of its triangles are the same, we have AB = BC = CD = AD = 30 feet.
On simplifying , we get
P = 4 ( 30 feet )
So , P = 120 feet
Hence , the perimeter is 120 feet

Mary, Bianca and Steve are picking apples. Mary picks 264 apples. 1/6 of these apples are green. Bianca picks 150 apples. 28% of these apples are green. Steve picks 340 apples. 15% of these apples are green. Who picks the most green apples? You must show your working out in your workbooks.
Answer:
Steve picked most green apples among the three people.
Step-by-step explanation:
Given that:
There are three persons Mary, Bianca and Steve who are picking apples.
Few of the apples are green.
We have to find the person who picked the most number of green apples.
Let us first calculate the number of green apples picked by each one of them then we can compare the three values to find the required answer.
Total number of apples picked by Mary = 264
Number of green apples picked by Mary = [tex]\frac{1}{6}[/tex] of the total apples picked by Mary = [tex]\frac{1}{6}\times 264 = 44[/tex]
Total number of apples picked by Bianca = 150
Number of green apples picked by Bianca = 28% of the total apples picked by Bianca= [tex]\frac{28}{100}\times 150 = 42[/tex]
Total number of apples picked by Steve = 340
Number of green apples picked by Steve = 15% of the total apples picked by Steve = [tex]\frac{15}{100}\times 34 = 51[/tex]
We have 3 numbers now, 44, 42 and 51.
Clearly 51 is greatest of them all.
Therefore, Steve picked the most green apples.
