Answer:
2.5 pounds of cashews.
Step-by-step explanation:
Let's say we have a for pounds of almonds and c for pounds of cashews.
6.5a + 5.5c = 23.5
6.5 * 1.5 + 5.5c = 23.5
9.75 + 5.5c = 23.5
5.5c = 13.75
c = 2.5
So, Ariel bought 2.5 pounds of cashews.
Hope this helps!
The number of books in her summer reading list is = 20
The number of books that has been read by Emma = 14
The percentage of books that has been read by Emma = 70%
But the percentage of books in Emma summer reading list = 100%
∴ The number of books in her reading list= ˣ
That is ;
70% = 14
100% = ˣ
Make ˣ the subject of formula,
ˣ = 100 × 14 / 70
ˣ = 20

Answer
Find out the value of x .
To proof
SAS congurence property
In this property two sides and one angle of the two triangles are equal.
in the Δ ADC and ΔBDC
(1) CD = CD (common side of both the triangle)
(2) ∠CDA = ∠ CDB = 90 °
( ∠CDA +∠ CDB = 180 ° (Linear pair)
as given in the diagram
∠CDA = 90°
∠ CDB = 180 ° - 90°
∠ CDB = 90°)
(3) AD = DB (as shown in the diagram)
Δ ADC ≅ ΔBDC
by using the SAS congurence property .
AC = BC
(Corresponding sides of the congurent triangle)
As given
the length of AC is 2x and the length of BC is 3x - 5 .
2x = 3x - 5
3x -2x =5
x = 5
The value of x is 5 .
Hence proved
One way to solve the system is to <u>substitute</u> a variable.
<u>Explanation:</u>
One approach to solve an equation is by substitution of one variable. Right now, a condition for one factor, at that point substitute that arrangement in the other condition, and explain. All value(s) of the variable(s) that fulfills a condition, disparity, arrangement of conditions, or arrangement of imbalances.
The technique for tackling "by substitution" works by settling one of the conditions (you pick which one) for one of the factors (you pick which one), and afterward stopping this go into the other condition, "subbing" for the picked variable and fathoming for the other. At that point you back-explain for the principal variable.
