Together, teammates Pedro and Ricky got 2675 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each player have?
Answers
Answer:
1199 for ricky, 1476 for Pedro
Step-by-step explanation:
2675-277=2398
2398 / 2 = 1199
each player had 1199 bases, pedro however, had 277 more bases than ricky
1199 + 277 = 1476
By solving a system of equations, we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.
How many hits did each player have?Let's define the variables:
P = base hits of Pedro last season.R = base hits of Ricky last season.Then we have that the total number of base hits last season is 2675, so we have:
P + R = 2675
We also know that Pedro has 277 more hits than Ricky, then:
P = 277 + R
To solve these equations, we can replace the second equation into the first one:
P + R = 2675
(277 + R) + R = 2675
2*R = 2675 - 277 = 2,398
R = 2,398/2 = 1,199
So we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.

game. If he earns $9 per hour at his part-time job, which equation can be used to find the
number of hours, h, Javier needs to work to have enough money to buy the video game?
Answers
Answer: 9h + 20 = 62
Step-by-step explanation:
he has 20 dollars now he needs 42 more so 9h is how much he earns multiplied by h how many hours he needs to work and you would add 20 onto that for the money he already saved and set that equal to the amount he needs
The perimeter of a rectangular garden is 338 m.
If the width of the garden is 74 m, what is its length?
Answers
Answer:
l=95
Step-by-step explanation:
Perimeter is all the sides add up. So the equation if you know two of the sides, it should be: 338=(2*74)+(2*l)
Answer:
Step-by-step explanation:
the perimeter is 2w plus 2l
so 338 = 74(2)+2l
338 = 148+2l
190=2l
l=95
your length would be 95 m

(-5,-7) and (3,1)
write equation in point slope form, intercept form, and standard form
Answers
Answer:
Please check the explanation
Step-by-step explanation:
Given the points
(-5,-7) (3,1)Determining the slope between the points:
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-5,\:-7\right),\:\left(x_2,\:y_2\right)=\left(3,\:1\right)[/tex]
[tex]m=\frac{1-\left(-7\right)}{3-\left(-5\right)}[/tex]
[tex]m=1[/tex]
Writing the equation in point-slope form
As the point-slope form of the line equation is defined by
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Putting the point [tex](-5,-7)[/tex] and the slope [tex]m = 1[/tex] in the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-7\right)=1\left(x-\left(-5\right)\right)\\[/tex]
Hence, the equation in the point-slope form will be:
[tex]y-\left(-7\right)=1\left(x-\left(-5\right)\right)[/tex]
Writing the equation in slope-intercept form
As the point-slope of the equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Putting m = 1 and (3, 1) to determine the y-intercept
[tex]y = mx+b[/tex]
[tex]1 = 1 (3) + b[/tex]
[tex]1 = 3 + b[/tex]
[tex]b = -2[/tex]
so putting [tex]b=-2[/tex] and m = 1 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y = (1)x + (-2)[/tex]
Therefore, the equation in slope-intercept form is:
[tex]y = x -2[/tex]
Writing the equation in the standard form form
As we know that the equation in the standard form is
[tex]Ax+By=C[/tex]
where x and y are variables and A, B and C are constants
As we already know the equation in slope-intercept form
[tex]y = (1)x + (-2)[/tex]
so just simplify the equation to write in standard form
[tex]y = (1)x + (-2)[/tex]
[tex]y = x - 2[/tex]
[tex]y - x = -2[/tex]

Answers
Answer:
[tex]50^{\circ}[/tex]
Step-by-step explanation:
Complementary angles mean that the sum of the angles add up to [tex]90^{\circ}[/tex]. We can use algebra to solve for [tex]x[/tex] and then to determine [tex]m\angle QRS[/tex].
[tex]m\angle QRS + m\angle SRT = 90[/tex]
[tex]8x+10 + 8x = 90[/tex]
[tex]16x = 80[/tex]
[tex]x = 5[/tex]
[tex]m\angle QRS = 8x+10[/tex]
[tex]= 8(5)+10[/tex] (substitution)
[tex]=50^{\circ}[/tex]
∴ [tex]m\angle QRS = 50^{\circ}[/tex]

X, Y and Z form the vertices of a triangle, where ∠ YXZ = 68°, XY = 7.3m and XZ = 8.3m. Calculate the area of the triangle. Round your answer to 1 DP.
Answers
Answer: Area = 28.2m²
Step-by-step explanation: The triangle YXZ is shown in the figure below.
Area of a triangle is calculated by the formula:
[tex]A=\frac{1}{2} (base*height)[/tex]
According to the figure, the base of this triangle is b = 8.3m.
Height is a perpendicular line created from one side and intersecting the opposite angle.
To determine the height, use trigonometric relations to angle 68:
[tex]sin(68)=\frac{h}{7.3}[/tex]
h = 7.3*sin(68)
h = 7.3*0.93
h = 6.8
Now, area of triangle YXZ is
[tex]A=\frac{1}{2} (8.3*6.8)[/tex]
A = 28.2
Area of triangle YXZ is 28.2m².
