Answer:
x = 7
Step-by-step explanation:
5x - 1 + 8x + 5 = 95
13x + 4 = 95
13x = 91
x = 7
Triangle in 95° so x is
»8x + 5° + 5x - 1° = 95°
»13x + 4° = 95°
»13x = 91°
»x = 91°/13
»x = 7°✅
Use the scale to help you solve the equation.
x + 122
334
e
Answer:
A. x = 212
Step-by-step explanation:
This scale is showing us that x + 122 is equal to 334 because the scale is balanced and we can see an equal sign (=) in the center. We will set up an equation and solve for x.
[Equation]
x + 122 = 334
[Subtract 122 from both sides]
x = 212
A. x = 212
To make 100g of jam you need 41g of strawberries, 13g of blackberries and the rest should be sugar. What is the ratio of blackberries to sugar? Give your answer in its simplest form.
Answer:
13 : 46
Step-by-step explanation:
First, find amount of sugar.
= 100 - 41 - 13
= 100 - 54
= 46
Blackberries : Sugar
= 13 : 46
Answer:
13 : 46
Step-by-step explanation:
amount of sugar required = 100 - 41 - 13 = 100 - 54 = 46 g
ratio of blackberries : sugar = 13 : 46

Figure A, B, D have point symmetry.
What is point symmetry?Point Symmetry is when every part has a matching part the same distance from the central point but in the opposite direction. It looks the same when viewed from opposite directions (180° rotation).
Try imagining how each of the figure will look after rotating it for 180°. If it looks exactly same as the original figure, it has point symmetry.

you choose between red, blue, yellow or green wallpaper and purple or yellow carpet find the total number of possible outcomes when you select one color of wallpaper and one color of carpet
Answer:
8 possible outcomes
Step-by-step explanation:
I'm going to list all the possibilities and then count them up.
First Word is the wallpaper color, Second is the carpet color.
Red + Purple, Red + Yellow, Blue + Purple, Blue + Yellow, Yellow + Purple, Yellow + Yellow, Green + Purple, Green + Yellow
After counting them up, we get 8. Therefore there are 8 possible outcomes.
Another way is to multiply the possible outcomes for each event together, and you can get the total number of outcomes. For example, in this problem there is 4 wallpaper colors and 2 carpet colors, so when u multiply them u get 8 total outcomes. Hope this helped!

Mark is also trying to save money. He already has $3.00 saved and puts $1.00 per week away in
his piggy bank. This can be represented by the equation y = x + 3
¿Will Jen or Mark save $20.00 first? Justify your reasoning.
Answer:
Mark will save $20 in 17 weeks, but there is no equation for Jen.
Step-by-step explanation:
y = x + 3
1) replace y with $20
20 = x + 3
2) subtract 3 from both sides
17 = x

Find the sum of the arithmetic series
Answer:
The sum of the series = 198.Step-by-step explanation:
In the given arithmetic series,
The first term (a) = 6Common difference (d) = (aₙ – aₙ₋₁) = 10 - 6 = 4Last term (aₙ) = 38To find the sum of the series, we need to find the number of terms (n) at first. So,
[tex]a_{n} = a + (n - 1)d\\38 = 6 + (n - 1) 4\\38 - 6 = 4n - 4\\32 = 4n - 4\\32 + 4 = 4n\\36 = 4n\\36 \div 4 = n\\\boxed{9 = n}[/tex]
Now, let's find the sum of the arithmetic series (Sₙ).
[tex]S_{n} = \frac{n}{2} [2a + (n - 1)d]\\S_{n} = \frac{9}{2} [2*6 + (9 -1)4]\\S_{n} = \frac{9}{2} [12+ (8*4)]\\S_{n} = \frac{9}{2} [12+ 32]\\S_{n} = \frac{9}{2} (44)\\S_{n} = 9*22\\\boxed{S_{n} = 198}[/tex]
The sum of the series = 198._______________

Explain how you can convert a decimal that terminates after three decimal places to a fraction.
Answer:
First, let's just pick an arbitrary number as an example 7.031.
the 1 is in the thousandth place, so we can represent this as [tex]7\frac{31}{1000}[/tex].
This is so because determining what denominator of a decimal number is can be known through what non-zero digits is on the right-most side of the number.
Step-by-step explanation:
Answer:
The third digit after a decimal point is in the "thousandth" place.
Therefore, to convert a decimal that terminates after three decimal places to a fraction, simply write the digits (without leading zeros) as the numerator and 1000 as the denominator.
For example:
[tex]12.345=\dfrac{12345}{1000}[/tex]
[tex]0.932=\dfrac{932}{1000}[/tex]

please help me solve this equation asap i have 100 marks exam tommorow!
Answer:
a) i) y = - 5/3
ii) y = 4/3
b) i) x = 1
ii) x = -3/4
Step-by-step explanation:
[tex]y=\dfrac23x +\dfrac13[/tex]
a) i) [tex]x=-3[/tex]
[tex]\implies y=\dfrac23(-3) +\dfrac13\\\\\\\implies y=\dfrac{-6}{3} +\dfrac13\\\\\\\implies y=\dfrac{1-6}{3} \\\\\\\implies y=-\dfrac53[/tex]
ii) [tex]x=1\frac12=\dfrac32[/tex]
[tex]\implies y=\dfrac23\left(\dfrac32\right) +\dfrac13\\\\\\\implies y=\dfrac{6}{6}+\dfrac13\\\\\\\implies y=\dfrac{3}{3}+\dfrac13\\\\\\\implies y=\dfrac{3+1}{3}\\\\\\\implies y=\dfrac43[/tex]
b) i) [tex]y=1[/tex]
[tex]\implies \dfrac23x +\dfrac13=1\\\\\\\implies \dfrac23x =1-\dfrac13\\\\\\\implies \dfrac23x =\dfrac23\\\\\\\implies x =1[/tex]
ii) [tex]y=-\dfrac16[/tex]
[tex]\implies \dfrac23x +\dfrac13=-\dfrac16\\\\\\\implies \dfrac23x =-\dfrac12\\\\\\\implies x =-\dfrac12 \div \dfrac23=-\dfrac12 \times\dfrac32=-\dfrac34[/tex]
