Answer:
Robert Recorde.
Step-by-step explanation:
Robert Recorde was a Welsh known for vast knowledge and experience in the field of mathematics and physics. He was born in Tenby, Pembrokeshire, Wales during the Medieval period (c. 1512).
Robert Recorde was famously known for his work in the field of mathematics and most especially, the invention of the equal to (=) sign. He introduced it in his book titled "The Whetstone of Witte."
Hence, Robert Recorde was the first english mathematician who first used the modern symbol of equality in 1557.

IF NQZ IS SIMILAR TO CBK, FIND BK
Answer:
Bk = 65
Step-by-step explanation:
BK as we can see is 4x + 1
If two triangles are similar, the ratio of the corresponding sides are the same
Thus;
2x+7/27 = 4x + 1/45
45(2x + 7) = 27(4x + 1)
90x + 315 = 108x + 27
108x-90x = 315-27
18x = 288
x = 288/18
x = 16
From the question;
BK = 4x + 1
BK = 4(16) + 1
BK = 64 + 1
BK = 65
9. If AT = 2x + 1, TL = 15, and AL = 7x + 1, select ALL that are true.
Answer:
B. x = 3
C. Segment AT = 7
F. Segment AL = 22
Step-by-step explanation:
To figure out what the length of Segments AT and AL are use the equation ((2x + 1) + 15) = 7x + 1.
((2x + 1) + 15) = 7x + 1
Add 1 to 15 to get 16.
2x + 16 = 7x + 1
Subtract 7x from both sides. This cancels the +7x.
2x + 16 - 7x = 1
Combine 2x and -7x to get -5x
-5x + 16 = 1
Subtract 16 from both sides. This chancels the +16x.
-5x = 1 - 16
Subtract 16 from 1 to get -15.
-5x = -15
Divide both sides by -5. This cancels the multiplication by -5.
x = -15/-5
Dividing any two negative numbers ends in a positive. Divide -15 by -5 to get 3.
x = 3
Now, substitute x for 3 in 2x + 1 and 7x + 1 to figure out the lengths.
2(3) + 1
Mulitply 2 by 3 for 6.
6 + 1
Add 1 to 6 to get 7.
Segment AT is 7 units long.
7(3) + 1
Multiply 7 by 3 to get 21.
21 + 1
Add 1 to 21 to get 22.
Segment AL is 22 units long.

Answer:
6qt + 1p
Step-by-step explanation:
In a question like this, one can only combine like terms, in other words, the coefficients of the same variables. A coefficient is the number that is in front of a variable or the number a variable is being multiplied by.
The equation is;
4qt + 2qt + 1pt
4qt and 2qt are like terms, hence one can combine them.
The result is;
6qt + 1pt

A25f oz. botie of Tide detergent costs $3.99 and a 90 fl oz. bottle of Tide detergent costs $6.99. Is the 25 oz or 90 oz bottle of Tide a better
buy?
Answer:
The 90 oz bottle of Tide is the better buy because it has a lower price per oz.
Step-by-step explanation:
To find the bottle of Tide that is a better buy, you have to divide each price for the number of ounces they have and determine the one that has the lower price per ounce.
$3.99/25= $0.15
$6.99/90= $0.07
According to this, the answer is that the 90 oz bottle of Tide is the better buy because it has a lower price per oz.

tabitha has 1/2 loaf of bread she need to slices in 9 equal parts how many pieces will there be
Answer:
1.3
Step-by-step explanation:
i really duno thow
Answer:
1/18
Step-by-step explanation:
we are doing 1/2 divided into 9 parts so that would be 1/2 / 9 but when we divide fractions we turn one of the fractions upside down and instead of dividing we multiply so it would look like 1/2*1/9 = 1/18

A line with a slope of 10 passes through the point (0, 10). What is its equation in
slope-intercept form?
Answer:
y = 10x + 10
Step-by-step explanation:
(0,10) means that the y is 10 when the x is 0, which is the y-intercept
y-intercept: 10
b = y-intercept
m = slope
slope: 10
y = mx + b
y = 10x + 10
-x + 4 = x + 6
What the answer to this
Answer:
All you need to do is balance the equation.
x = -1
Step-by-step explanation:
Find the slope of the ordered pairs (2,5) (4.13)
9514 1404 393
Answer:
4
Step-by-step explanation:
The slope formula is useful:
m = (y2 -y1)/(x2 -x1)
m = (13 -5)/(4 -2) = 8/2
m = 4
The slope of the line through those points is 4.

A can holds 345 milliliters of orange juice. How many liters of orange juice is
this?
Metric Units of Capacity
1,000 milliliters (ml) = 1 liter (L)
100 centiliters (CL) 1 liter
10 deciliters (dL) = 1 liter
1 dekaliter (dal) = 10 liters
1 hectoliter (L) = 100 liters
1 kiloliter (KL) = 1,000 liters
Answer:
0.345 L
Step-by-step explanation:
so we know that 1L = 1000 mL
now we have 345 mL so it equals 0.345 L
