3x-2=3
3x=3+2
3x=5
x=5/3
Answer : According to the information provided in the question, the value of 'x' is 5/3
Answer:
we say 3x equal to 5
divide everything by 3
which will give us 1/2/3
The electric current is I, is amperes, in a circuit varies directly as the voltage V. When 12 volts are applied the current is 4 amperes. What is the current when 18 volts are applied
Answer: 6 A
Step-by-step explanation:
Given
Current varies directly with Voltage
i.e.
[tex]I\ \propto V\ or\\V\ \propto\ I\\V=IR[/tex]
when V=12 V, I=4 A i.e.
[tex]\Rightarrow 12=4R\\\Rightarrow R=3\ \Omega[/tex]
When V=18 V
[tex]\Rightarrow 18=I\times 3\\\Rightarrow I=6\ A[/tex]
Current is 6 Ampere
The radius of a regular hexagon is 8 cm.
Find the apothem, perimeter and area
of the regular hexagon.
the measure of the side = of the measure of radius because the regular hexagon have 6 sides = at each others
meaning the measure the perimeter is = 6 times the radius
and the radius = 8cm
so perimeter = 6× 8 cm
perimeter = 48cm
since the apothem is the segment perpendicular to a side thought the center and those segment are not promotional we have the notation as
r square root of 3 divided by 2
r = radius = 8 cm
by apply the formula
8square root 3 divided by 2
so the area will be
since the perimeter is 48cm
and the apothem is 8 square root of 3 divided 2
so the area will be 48 times 8 square root of 3 divided by 2 = 384 square of 3 divided by 2 .
hope that helps.
Find the limit of the function by using direct substitution. limit as x approaches three of quantity x squared plus three x minus one.
17
0
-17
does not exist
Answer:
17
Step-by-step explanation:
Given the limit of a function expressed as;
[tex]\lim_{x \to 3} x^2 + 3x - 1[/tex]
Substitute x = 3 into the function to have;
[tex]= 3^2 + 3(3) - 1\\= 9 + 9 -1 \\= 18 - 1\\= 17[/tex]
Hence the limit of the function as x tends to 3 is 17

The slope-intercept form of the equation of a line that passes through point (–2, –13) is y = 5x – 3. What is the point-slope form of the equation for this line?
Answer:
y + 13 = 5(x + 2)
Step-by-step explanation:
the point is (-2 , -13)
Point slope form is: y - y1 = m(x - x1)
y1= -13
x1= -2
y - -13 = 5 (x - -2)
y +13 = 5(x+2)

aster sold 18 oranges if this are 12% of her total oranges how many oranges are not sold
Answer:
132.
Step-by-step explanation:
If 12% are sold then 100-12 = 88% are unsold.
12% = 18 oranges
1% = 18/12 = 1.5 oranges,
88% = 1.5 * 88 = 132.

Triangle = (12 x 48) / 2 = 288 in2
total area = 1536 + 288 = 1824 in2
Sally's age is 2 plus 3 times John's age. Together, Sally and John's age equals 30. How old is Sally?
Answer:
Sally is 23 years old.
Step-by-step explanation:
John's age is completely unknown, so it is known as x
Meanwhile, Sally's age can be represented as 3x+2
The sum of both ages is 30.
So, x+3x+2=30
Combine like terms.
4x+2=30
Subtract 2 from both sides.
4x=28
Divide both sides by 4.
x=7
John is 7 years old.
Sally's age: 3(7)+2=23
Sally is 23 years old.
give the value of x for the equivalent ratio 3:8 x:24
Answer:
9
Step-by-step explanation:
3/8=x/24 (cross multiplication)
3*24=8x (we don't need to multiply 3 with 24 bc we will divide both sides by 8 so it will be easier to find the final value)
x=9
Answer:
x = 9
Step-by-step explanation:
8: 24
Multiply 3
8 x 3 = 24
3 : x
Multiply 3
3 x 3 = 9
x = 9

I have attached the complete question with the triangle.
Answer:
x = 6
Step-by-step explanation:
From the image attached we are told to find x in the triangle.
The triangle is a right angle triangle and so we can use pythagoras theorem to find x.
x² = 6.5² - 2.5²
x² = 42.25 - 6.25
x = √36
x = 6

Step-by-step explanation:
Rico spins the spinner twice and determines the sums of the spins. Fill in the sample space to determine the possible outcomes. What is the probability that Rico will get a sum less than or equal to 8? A 13\frac{1}{3} 3 1 B 23\frac{2}{3} 3 2 C 89\frac{8}{9} 9 8 D 59\frac{5}{9} 9 5
Answer:
2/3
Step-by-step explanation:
Sample space for the sum of 2 spins :
Number on spinner = 2, 5, 4
____ 2 ___ 5 _____4
2___ 4 ___ 7 _____ 6
|
5___ 7 ___ 10 ____ 9
|
4___ 6 ___ 9 ____ 8
Hence,
(4, 7, 6, 7, 10, 9, 6, 9, 8)
Probability of getting a sum less than or equal to 8;
Probability = required outcome / Total possible outcomes
Required outcome =, sum ≤ 8 = 6
Total possible outcomes = 9
P(sum ≤ 8) = 6/9 = 2/3
Two sides of a triangle have lengths 7 and 15. Which inequality represents the possible lengths for the third side , x?
Answer:
8 < x <22
Step-by-step explanation:
In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x
One one side of the inequality we have:
7+15>x
22 > x
On the other side we have
7 + x > 15
X > 15-7
X>8
When we rearrange these inequalities above we have
8<X<22
We saw from the calculations that 8 is less than X and X is less than 22.
